Nikkor 18-200mm or Sigma 18-250mm?

I'm going to be using this lens on my Nikon d3200 for travel and general all around shots. Right now I can get the Nikkor 18-200mm for $350 (slightly used, very good condition) and the Sigma 18-250mm for $350 (new). I have used the Nikkor 18-200mm a few times and generally like it except the fact it is a little on the heavy size and like other lenses it has barrel creep (which I don't mind too much). I haven't used the Sigma 18-250mm so I can't say anything for that one. Which one would you purchase and why (please list some pros and cons) thanks!

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.
