You're basically describing D&D Gladiator pits. Real gladiators would fight for sport, not usually to the death, and gain tons of experience before going off to be wound treated. Some were slaves and some were mercs in it for money. But whatever the case, they definitely learned some things. Not so much how to slay giant dragons and demons but some things.
