This is almost certainly true, except for the "stats that matter" bit. If you want to sell an app today, iOS is still the platform to target first. But that's not a stable position.
If Android becomes the platform that "everyone" has, then the next disruptive consumer change is, almost by definition, going to happen there. This is largely what happened to the Mac -- the platform that had the best of everything in 1988 was, by 1994, suddenly unable to run all the new toys everyone wanted. When Win95 was released it wasn't even all that technically superior anymore. And by 1998 it was almost dead (and, but for the iPod's success, probably would have died).
