Can you really play games and earn money?

So, I've heard that there are platforms that allow people to play games and earn money. Is this really a viable option, or is it just another one of those too-good-to-be-true schemes? Can you elaborate on how this works, and what kind of games are typically involved? Also, what are the potential risks and rewards associated with this type of earning opportunity? I'm interested in learning more about this trend and whether or not it's worth pursuing.
