There are lots of people writing blog posts complaining that their apps don't earn them money. Conventional wisdom right now seems to be that it's normal that developers don't make any money. But it is very much possible to make a money selling apps. Just identify a market that you can serve, then make a good app, then advertise it effectively. Profit! However, it's not easy to become a billionaire with your app; for that you need lots of luck among other things. I think the comparison with acting is actually pretty good. There are a lot of people who make money acting. It's not that difficult. You need a bit of talent and a lot of commitment, but I happen to know more than one person who managed to become professional actors. It is of course unlikely to become a world famous super-rich actor; but making a reasonable living from acting is absolutely achievable.
