Slightly different direction. You are talking about starting your own business or building your existing business that just happens to be in a YouTube format. Is your channel generating enough money for you to live happily or can you reasonably forecast and execute what would need to happen to get there? If you can, congratulations, you are a young business owner!
If not, you might want to consider whether you (and your loved ones supporting you) are willing to accept whatever that lifestyle would be (not judging.) In this case, maybe college makes sense while waiting for your channel to mature. Perhaps there are business classes that would help you. There’s no reason you can’t pursue both.
That being said, if you decide to pursue it, treat it like a business. Write a business plan (there’s probably a channel to show you how) and present it to several adults you respect. Listen to their criticisms. Decide If this is a hobby or a business. If it is a business, have a plan B - many businesses fail. Think about what you’ll need if that time comes. That’s where the degree is handy. Good luck!
