The biggest region in term of revenues for Apple revenues is all americas but it is still only around 43%, which means Apple still makes money from Africa, Europe, Asia and Ocenia combined than the whole american continent. So that is even less for the USA.
You are doing a lot of heavy lifting lumping Europe and Asia together, and inserting Africa and Oceana, which is so small Apple doesn't even report revenue for it.
North America is 43%
Europe is 27%
China 15%
Japan 7%
Rest of Asia: 8%
Africa, middle east, oceania effective round to 0%
Basically North America and Japan make up 50% of Apple's revenue, but are nowhere near 50% of global GDP or population.
India has 1.3 Billion people in terms of counting mouths, but not wallets with $1000 to send to Apple for a new iphone.
