"Most people fail, so better don't even try."
Is this genuinely the advice you'd give to someone who's less experienced in life? No wonder society is the way it is, most people have extremely low ambitions and then don't even bother working on those.
I think you're ignoring the GP's last paragraph.
Maybe an intermediate position is to say, "Before you attempt to beat the odds, make sure you can survive the odds beating you." Because the odds are, they will.
