Surely the litmus test of an all time global great is being revered outside of his or her base, by a wide range of countries and cultures? Often even transcending their particular sport? It isn't just a head count. Being huge in one heavily populated area is basically just stat padding. If China's most successful Popstar sold as many records as the Beatles, but only in China, would you claim he/she deserved to be considered amongst the GOATs?
IMO, it's probably less to do with Western ignorance (the English invented Cricket after all) and more to do with Cricket's general lack of traction. Of all the old Anglo public school originated passtimes, Football became the biggest not because it was a uniquely cool English thing forced on people during the height of the Empire (that was Cricket, if anything*) but because it was the one that organically caught on across the broadest global demographic. Yes it's helped by being big in a number of culturally important "cool" Western places, but it's also big in Africa and Asia, and famously unpopular in the World's current cultural arbiter of cool, America - which alone should disprove any notion of some nefarious Western sporting hegemony.
Even in America, where their inaccurate brand of football is the most popular domestic sport, and Baseball is considered the 'National passtime' it's Basketball that has the biggest global traction, and
their stars most of us outside Trumpistan are familiar with, because it's the one with the largest reach outside of it's base. The one played and watched by the greatest smorgasbord of disparate peeps.
Ranked by the number of National Federations, Cricket wouldn't make
the top 30...It'd even be below Rubgy, which is the sport it probably has the most in common with, being both spawned from the primordial sporting soup of 19th Century England, but still only of any genuine cultural significance to Commonwealth countries we basically forced to play it in the first place (*see above)...It had just as much chance of catching on as Football or Tennis, but it didn't. It's Free-market Sportenomics.
If anything I'd argue pushing for Tendulkar as an all time Sporting legend alongside the likes of Ali or Pele, displays more cultural myopia on your part, as it's presuming that a figure
you consider important, from a geographically parochial sport, should automatically be considered so by the rest of the largely non-Cricket playing/caring world.
It's kinda like me berating you for not knowing who Jhang Jike (the Chinese Federer of Ping Pong, btw) is.
But anyway, Tennis. What's up with that these days?
