Is there such thing as being a natural born fighter?

In my life I got into fights and most of the time is was with multiple people but I black out when ever I fight but then I find out when the fight is over that I won I don't even know how to really fight (I think)when I was in 1st grade I got into a fight with 3 people blacked out and won in elementary a fight with 11 people and I blacked out and won in middle school a fight with the school bully I won I am not sure if blacked out is the right term more or less forgot everything that happened during the fight only to find out I won by either people telling me i did ,all the kids running away crying,or people pulling me off the kids but I always win so is there such thing as being a natural born fighter because I don't even know how I won especially with those odds
