Doing any sort of online content creation as a primary source of income as a bad idea... unless you can make millions of dollars in a few years. It's basically gambling. I know someone who makes their primary income off online content. After a decade of 80-hour work weeks, he was finally making about 60k before taxes and his income stream has already fallen in two years from that peak to about 50k. Imagine putting that much time and effort into anything else, you'd probably be doing better than that and you'd have marketable skills and business connections. He also is depressed, despises his fans (who are basically all children or man-children), and would probably stop doing it if he had any other options. But he doesn't.
And if you can make that much money, then you should get in, get that bag, and get out before the mob turns on you or you lose relevance. But that requires you to understand your luck and have some business acumen and understanding of the value of time, effort, and money. If you had those things then why would you be betting on an algorithm-driven, quantity-over-quality, content-saturated place like Youtube or just about any other online platform?
