I have no idea how good that kart is, but if you're just starting out, I'll bet it's better than you are. I'm not putting you down one single bit you understand, but it takes time, and the learning curve is very steep, getting to the point where you'll be better than the kart.
If you've just started out, and you know nothing about setup, that kart will serve you well while you learn. Even buying the best of everything, you're never going to see a newcomer jump out into the lead in his 1st few races. And maybe more than a few.
