I believe in order for that to o current, you need to have a good plan. I am actually sort of in the same boat but for the gaming realm. It's something I enjoy to do in my free time so I might as well try bc it is fun. But once/if you get to a point where you know there is a chance for you to follow your passion..... Do it but be smart.
Study business a bit, not take classes or a degree but inform yourself well of business tactics. Simple things like branch out. Don't stay on YouTube forever. Eventually grow and move your fan base to your website and that you can have full control of. Invest your money wisely in your "small business", bc essentially that is what it will be.
Always be learning for bigger and better opportunities. Always stay informed in your industry or you will be left behind.
Anything is possible these days, I mean look at the presidency here in the US. Whether you agree or not with what happened, one thing for sure is that anyone can be one who they want to be in this country so long as they work their a** off.
Wish you the best, and don't give up.
