How Much Do Some of These Console Streamers Make Per Month off Twitch?

I’m genuinely just curious. I have no idea…do they make enough to just cover some bills? Can they live completely off of it? Do they also get partnership deals with the game, such as free skins/G-Coin/etc.? I’m talking about some of the more popular CONSOLE streamers too like Vurt, JTxTheSniper, Feyd, GaGod, etc.
