But they were. Their xG was 2.2 or so, and ours was 0.96. They had almost double the shots we had, they had more than double the shots in goal than us, they had 12 corners to us 4, and they had 57% possession. They had around triple the number of touches in our zone compared to us in their zone, and they had more than double the number of passes in the final third compared to us. They were definitely far better than us.
Could we have won the match though? Absolutely. I think that Hojlund's case was more than pen than not, that Garnacho was marginally offside and that Saka could have been sent off. If even one of those decisions would have gone in our favor, we could have easily ended with 3 points, or maybe with one, despite that Arsenal were the superior team. Same as how we ended with 3 points despite that Wolves were the better team.
