Specifically, what does it mean it someone lives on welfare? does it mean they receive money from the government?

Also, is living on welfare not enough to avoid ending up homeless? because i know of a guy, he has been unemployed for most of his life, i asked him how does he manage to support himself financially since he's unemployed, he responded by saying "Welfare and I live with my Mother".

To me that sounds like, if his mother was dead, he is at high risk of ending up homeless.
