It doesn't matter how tough you are, when you're outnumbered by entire prison gangs whose whole existence revolve around pumping iron and carrying weapons, you're completely fucked. For anyone to fault Gotti, Capone, or members of any biker gangs for not being able to stand up against that they watch too many movies or live in some sort of fantasy land. It's not even anything personal, these guys simply went from their world out on the streets to the world of prison gangs. That world belongs to THEM, it's just the way it is.
