The 3 ways to make money in gaming are to a) be exceptionally good at games, b) have an entertaining personality, or c) do something that nobody else does.

For a) either you’re good enough to make it in esports, or you’re good enough that people want to watch you stream. For b) gaming is really just a small part of what brings people in. c) might be doing things like challenges or other niche gaming related stuff.
