Is there a good possibility this could become a career?

So I am almost 15 and am starting kickboxing, I want to be a fighter, MMA. I have had a few street fights and i love the feeling you get when in a fight, the entire experience of hitting, getting hit, everything. So how should i go about trying to achieve this goal as in what styles of fighting, is it possible etc? Also would it be necessary to go to a college when i leave school and get a trade in something or work in a shop while i work towards this ambition? Just wanted to know early so i know what i need to be doing in the meantime.
