Can you win real money on online games?

I'm curious, can you actually win real money by playing online games? I've heard of some platforms that offer cash prizes or even cryptocurrency rewards for winning certain games, but I'm not sure if they're legitimate or just a scam. Is it possible to make a profit from playing online games, and if so, what are some reputable platforms that offer these types of rewards? Additionally, are there any risks or limitations to consider when trying to win real money through online gaming?
