Would my martial art be any help to me in a real fight?

I take a form of karate called t.a.m.a( total aproach to martial arts) in boston m. It is not very traditional and infact it is more like a hybrid or mixed martial arts. There is not just a lot of kicks and punches, but a bunch of grappling and takedowns. The school allows for a lot of sparring to take place with gloves and protection. I also do amature wrestling and i have done a few techniques in my sparring( i aslo do a lot of sparring without protection but with gloves, and i do it with a bunch of friends). But what i want to know is that when i have to fight someone who wants to d me harm will this help me. Will i have an edge because of my martial arts traing, or will adrenaline just make me forget all i have learned and fight more like a drunk than a martial artist. I am in good shape and can take a solid hit. And when i say martial arts i don';t mean crazy movie stuff that obviously wouldn't work in a fight, i mean realistic things that i have trained in
