I think you can experience some humbling events, but teaching people to be humble isn’t exactly the goal of any of the martial arts. Lots of people just end up learning how to be more effective at violence. I used to do some amateur boxing, and I wouldn’t really claim a lot of the guys I boxed with to be especially humble. Lots of contact sports has a lot of ego involved in it.
