Just regard whatever you read about "being killed in training" as "full of crap", and you will be perfectly fine.
Sorry, full of crap, not! Rare, perhaps very, very, very rare, even in Japan where there is some history but it does happen. I also know of one student who was paralyzed during warm ups when a student rolled into her and another who had a stroke because she was kicked in the head, just right, and it damaged an artery. I don't know of any deaths here in the US within a dojo but there's probably been one somewhere at some time.
On the other hand, people have died playing basketball, tennis, football, boxing and 40,000 people will die in car related deaths this year.
