ELI5: When someone is choked until unconscious, what separates them from waking up (like in UFC fights) and dying?

A choke cuts off the blood supply to the brain causing unconsciousness.  You would have to maintain the choke for a much longer period to starve the brain of oxygen to kill a person.  Just think of how long strangulation takes to kill a person.
