That is not a statement of fact but a disclaimer of liability. I don't know how this plays out in other jurisdictions but it's hit epidemic levels here.
Some people get away with it though, like people with doctorates calling themselves Doctor on TV and giving out personal, relationship and medical advice while somehow managing not to be sued back to the Stone Age.
It’s illegal for a non-lawyer to claim to be giving legal advice, so it’s traditional to be clear that you aren’t doing that. (Of course, I’m not claiming to give you legal advice on this.)
