The problem with the "people I know" stats is that people we know are generally people like us, maybe family (much like us), and friends (probably more like us than not), etc. For instance, almost all people I know are white Americans who live in Florida, but that doesn't mean that ALL people are white, all are Americans, and all people only live in Florida. It can certainly look like that if I "poll" only "people I know" but that's the common mistake many of us make when we're slinging around our "99.9%" claims and so on... often based on a survey of as little as just the lone person writing the post.
Android:ios is rapidly becoming Windows:macOS. That's not putting down iOS, macOS or Apple, just pointing out that this is basically a repeat of decisions made from when Apple had THE mouse & windows-oriented OS and a challenger came along years later... who then proceeded to make decisions to catch up and then take over the dominant share of that market.
Deja Vu?
