I wonder if this statement is true. The reports I read about Android vs iOS revenue are US market only, or about e-commerce payments.
I'm an app developer and we make a lot of money developing apps that never end up in the app stores. They are in-company apps, both Android and iOS apps.

It is mostly 'has been repeated to death so it must be true' statement.
The reality, as always, is way more complicated. Outside of the US market, Android and iOS have very comparable high end marketshare.
Depending on your niche and your business model, the good choice for your app can vary from one opposite to another.
