I agree with you but at the same time I feel like I should point out that this is the China fallacy, where there's a billion people in China and if you could just tap into even 0.3% of their market you would make bank.
While it's technically true, the fallacy behind it overshadows the difficulty of acquiring that percentage of the market. The grand majority of games released never become cash positive, and over 50% of games on steam alone never make more than $4,000.
This is not an issue with distribution, it's an issue with marketing and market fit, and accompanied by the base fact of that if you're the kind of person who is good at making games, it would be a rarity for you to also be the kind of person that's good at marketing the games you made.
Those are two entirely different wheelhouses that function best with two entirely different personality types, and that's not covering all of the different disciplines that you need to make a game or run a game making company in the first place.
