Could this be more of a mocking of how France poaches players and talents from all over Africa and yet "we" beat them?
It is not the French national team that is being sung about. It is Mbappe, and players who have apparently have roots in Angola, Cameroon, and Nigeria. The country of France is clearly not being mocked, specific French players are. There is nothing in the chant about Argentina beating France, either - no place where the 'we' is implied.
Is the premise of the chant any different from the one used by Trevor Noah for this segment?

In your clip, the premise for Trevor Noah's joke is that there are many African-origin players in that French squad. Which is a fact. 'You don't get this tan in the south of France' is the joke based on this fact. But that's where the similarity ends.
Firstly, Trevor Noah is of African descent himself. And he is performing comedy on live television. There is a performative nature to his act, which means not everything he says is a belief or the truth, but a made up narrative in which he was joking about origins he shares himself. A white comedian making the same joke? Problematic, because it's punching down - but he's still performing, so maybe he doesn't truly believe in the act. A white comedian saying the same thing but in private, while being secretly recorded? Even more problematic, and perhaps no longer a 'joke' - it indicates belief. Secondly, Noah's joke celebrates African heritage instead of being derogatory towards the players' French nationality. There is no hate.
In contrast, the Argentine players are white, and not doing a comedy bit at all. There is an obvious derogatory depiction of Mbappe (and the 'they', which is players like him, clearly referring to race given the countries mentioned). The premise is still the same, but now there is a lot of hate. There's a difference between stating 'a lot of the French players are of African origin' (a fact), and 'they are all from Angola' (a derogatory generalization which is dismissive, and we know present in this song only for rhyming patterns). Also, the way the song contrasts between the countries of birth and the document of nationality clearly undermines the identity of the players - reduces them to the color of their skin, takes away their national pride - as if to tell them 'you don't belong in this country'. It implies a belief that white people can belong to the countries their families have migrated to, but black people cannot. Superiority of a race over another. Racism.
When USA beat Pakistan in the T20 cricket world cup. Many were joking about how India's H1B team (and not USA) beat Pakistan. Is the Argentina song about the nationality of the player's parents any different?
Again, celebrating the US players' Indian heritage, rather than undermining their sense of nationality or belonging to the US. If it were the bolded bit you've included (which I've not encountered, but possible) then it becomes racist. If it were non-Indians/non-Americans singing chants about the Indian origin players, stating how they are all from Bombay, being transphobic towards one of them, and then ending with 'In green card -USA', indicating that the players don't belong to the US national team, that would definitely be racist, as well.
These players have exposure, have colleagues and friends who have roots in Africa and play for Franch/Netherlands/Germany etc. Can we not assume the best in them and think that all this is not coming from a bad place. Is it possible this is healthy banter?
The outrage is because there players have exposure, colleagues and friends with roots in Africa, they should know how it is racist to sing such chants. That it is not from a sense of ignorance, but of indifference. It's because Enzo did not cut his stream for the first chant, but did for the second. He knew it is wrong, but didn't care. Excuses like 'the chant is catchy', 'they have African friends' are just that - excuses. You can assume the best in them in incidents like Cavani's - where his cultural roots prevented him from knowing possible interpretations of the word negrito. When international footballers like Enzo - playing at diverse clubs like Chelsea, actively bending the knee at kick off for a cause along with his team, holding up banners, wearing shirts with slogans and participating in anti-racism campaigns - do this, it is necessary to not assume the best anymore.
