Well, games don't really make a lot of money, unless you are King or another mobile giant, or make CoD or Fifa. I work at one of the largest games companies in the world, and all I can say is that for every game that makes millions of dollars, we have 20 projects that never even see a public announcement and eventually die, yet still cost us tons of money. That's where most of the money goes.

But yeah, programmers are hilariously underpaid, until they get to Senior level or above - there's just loads of people to fill junior positions.
