I haven't had a lot of martial arts training but I have been in a couple scraps in my life. I've seen a lot more. I've hung out in plenty of beer joints, bars, honky tonks, dance clubs and such. Some in Germany, and plenty throughout the South and Midwest. I've seen quite a few real life fights, I've been in a few, I used to be a bit reckless and wild. I've since grown up. Anyway, I thought I would share my experiences. Martial arts DOES give you a HUGE advantage, BUT it can also give you a big disadvantage. If you are the type that brags about your abilities then your potential opponents have time to prepare and adapt. If OTOH, you are quiet about your abilities then IF you have to fight then you have the advantage. Your opponent is ambushed by someone who knows what they are doing. I've seen 120 lb black belts whip up on huge guys but I've also seen big black belts who have been beat down by untrained people who simply knew how to fight and could absorb punishment. I think all in all it comes down to the person. But some training never hurts.
