That about the odds to be killed in a year for a Russian volunteer signing up to go to Ukraine. They do it for just $3k/month - for many Russians it is a great money and thus they risk their lives. Giving the limited options, it may as well be that many gladiators were happy to fight in the arena instead of dying from hunger and exhaustion in say quarry.
