Essentially the probabilities you meet in standard probability theory (stochastic processes, probabilities use in betting, e.t.c.) have mathematical properties that imply they result from your lack of knowledge about the system. The probabilities in quantum mechanics break these relations and imply the probabilities are fundamental, that there is no "deeper truth".
I'm not sure I'm qualified to elaborate further. But that thread linked to does have more related to this topic.
