Then why would he say it? The implication that he thinks he's done something great is clear (not saying that he hasn't done great things, but the semantics of his statement are clear, "go away guy who hasn't made billions of dollars and come back when your bank account is full").
I didn't read anything about the relation between greatness and bank accounts. It seems like you want to paint him according to your existing preconceptions. I read, "I really do take this stuff to heart, and you're telling me I'm just in it for the money.". I'd probably fire back something similar at 2 am (and regret it in the morning).
I didn't read that Jobs thinks he's great or that his employees are stupid.
