I think you mean outside of the Bay Area. For PCs/Desktop Apple has like 12% market share in the US. 7% globally.
I once had a discussion with a coworker at a major company known for its app, where I was complaining about an Android bug and he genuinely asked "does anybody even use Android?" And I responded, "only the majority of users in every country around the world including the US. It's even 50/50 on our app!" Afterward, I found the internal numbers for employee use of the app was 96/4 in favor of iOS, and this included employees outside of tech and outside the US!
He, like so many others, was totally oblivious living in the Bay Area tech bubble.

You’re completely right that this doesn’t hold true for other countries, and that ignoring Android is not the play, though.
