I have to agree with you on this. I've built and sold several "successful" indie apps (iOS, macOS, Android) and almost all had sales well into the many hundreds of thousands $ per annum.

Where is he getting this $4,000 number from?

If you’d only get $4000 for a reasonably succesful app the store would probably have a lot less apps. You can’t run a business on that kind of money.
