They don't really make much from the YouTube ads though. You might make $2000 if your video hits a million views and chances are that money is going to be split between a crew of people. There is a reason you see all of them having their own does or their own merch or a long list of Patreon subscribers. If you actually want to pay the content creators, buy their stuff or subscribe to them via Patreon.
I remember when YouTube first came out. It wasn't a "career" there were no content creators. People made and uploaded videos because they wanted to. Then ads appeared on channels that were monetised, they got a cut. This I was fine with. Now non monetised channels have ads everyone has ads
