It honestly depends on their personal situation. Some may have gotten away or looked over (extremely rare and lucky), and some may have just survived.
The body is insane and will do anything keep us alive - that's it main job. Some people who go into shock manage to survive, as their body shuts off any unneeded parts - mental awareness, etc. Some people also may have just gotten lucky, and their bodies may have lived through what they went through.
I am hoping that these answers

if you would like, feel free to ask another question.
