I studied business and have a dual MBA in entrepreneurial management and marketing. I finished grad school when I was 24. I think it's important to study something you are interested in, even if you choose a different route after you graduate.
You do not HAVE to go to college to succeed. However the stats show that it helps. "In a study of 11,745 US leaders, including CEOs, federal judges, politicians, multi-millionaires and billionaires, business leaders and the most globally powerful men and women, it showed that 94% of them went to college."

I feel that your skills are more important than college, but college may help open the doors for you to display your skills more prominently.
One thing I will say is that I saw a lot of people in college who were lazy and didn't take it serious. They would get outworked by many people who do not have a degree. It's all about work ethic and what value you can provide. I was lazy for my first two semesters. I moved to south Florida with many distractions. Then I made up my mind that if I was already there, I might as well do my best. Ended up finishing undergrad with a 3.2 GPA (after starting with a 2.1) and then completed my MBA with a 3.8 GPA. (In the USA a 4.0 is the highest you can achieve, and 2.0 is barely passing)
If you decide to go to college, I would advise that you give it your all from the start. If you're in the classroom anyways, you might as well learn something. Give it your all in anything you pursue, be persistent, and don't give up at the first sign of adversity. Every business leader, artist, and successful person has overcome obstacles to get where they are today.
I like having a formal education, and also learning every single day online, through podcasts, forums, as well as conversations with others. I refer to this as a continuous education. Good luck in all that you pursue!
