ELI5: How does playing dead help animals survive? Doesn't it just make them a more convenient meal for a predator? Why would an animal presume an attacker would just stop attacking and walk away?

some animals only eat what they killed.  because eating dead animals carries risk of disease.  and apparently they aren't smart enough to tell the difference between something playing dead vs being dead for a while.  or it could be due to the animal thinking that it belongs to another animal and they don't want to get into a fight over it.
