The point is, train to fight an enemy that may have equal to more skills than you possess. Train in a way that will make you incrementally better at every session. Train for your environment, for the enemy you would normally face.
Most of all be able to recognize the threat early, OODA, where most fights are won even with rudimentary skills. Being ahead of the curve increases your chances exponentially. You could have all the ninja fantastic skills in the world, but if you are easily ambushed or have a non-existent awareness level where you can't see things/situations that are developing/escalating, your skills aren't worth shit.
