I don't know. A hole in the wall where fights are going on, is a pretty big giveaway. Unless the other guards in the arena are all "That slave is escaping... better not tell the rest" or "Let's not chase the girl through the hole."

It would all depend on if the other guards around don't see the hole or didn't see her going out the hole and don't know a little girl could possibly be the combatant they should be looking for (and that area is open to the general populace), and the girl gets out of range before the guards chasing her through the hole come out to alert the other guards of who the combatant is they should be stopping.
