I'm inclined to agree with Laroux and Lucas here. If you actually want to be able to "win" a street fight...your best bet is to train to fight, (the way a sport fighter would) and add concepts of dirty fighting.

If your method of training is to focus on conceptual dirty fighting, but not undergo fight training, I think your chances of success are significantly lower.

It's best if we can admit that "self defense" is western marketing gimmick. You can't sell TMA to suburban kids by telling their soccer moms you want to brainwash them to create a hardened fighter.
