I think you'd lose that bet. The kind of people who buy a lot of games are also the people who are not going to be tolerant of game compatibility issues on Linux; they want to play the game, not futz with their OS.
2 years ago I would have agreed with you, but the game compatibility issues really aren't there any more. Proton has made huge strides, and the Steam Deck has forced a lot of game companies to make sure that there aren't any issues.
