That's not what they mean. People who think they are broken will have been dealt a bad hand in life and our society's fundamental statute of "treat everyone the same by being equally shitty to everyone" means the same shit hits harder for the people with the bad hand and when they see other people with a better hand managing to deal with it they start to think that something is wrong with them.

That or a basic preconception of who/what/where they should be in life that they find themselves either not achieving or veering away from. It's that old "be a man" bullshit with a very strict view of what a "man" is and not enough wiggle room to accommodate who they really are.
