Photography as a career?

I'm 14 and ever since I've been 12 I've been really interested in photography. I started off with a digital camera, then a bridge then I saved all my money and bought a Nikon D3200 which came with a kit lens and I honestly don't think my photos are too bad haha. I want photography to be my career and I hope to get university and everything. But the only thing is I really don't understand things like ISO, exposure, what different shutter speeds do and all of that. So is it pointless in me wanting to be a photographer if I don't understand anything on a DSLR? All I know how to do is point and shoot…
Also is a NIkon D3200 a bad camera to have whilst doing my GCSE's/A Levels? Like is it high tech enough?

Any advice would be very helpful! So thanks a lot:)
