interesting odds question

[Cory Neely]

correct me if im wrong but somewhere in the back of the orignal super system there is a list of odds of being dealt 2 specific cards preflop. im a pretty smart guy and know that being dealt any 2 random cards out of a deck are the same as any 2 other random cards. what i want to know is why do the odds differ when he talks about getting pocket aces, kings, queens....? shouldnt they all be the same? if anyone needs clarification on what i am saying i will make the trip out to my car and get the book and quote the exact page and passage but currently i am too comfortable.
