Pocket Pairs Tripping UP

Last night in my weekly home game I had two people tell me that pocket 2's will trip up more often than pocket A's in Texas Holdem. They aregued this point for about an hour while i tried to teach them a little statistics. I guess it didn't work because they went home still arguing 2's trip up more than A's. I guess they think that the laws of mathematics apply in all of the world but not in cards or poker. I'm a young college kid and don't have much money but I offered to lay $1,000 on the table against one of them and they would have to run out the cards 10,000 times that there would be no statistical significance in the number of times that each will trip up. It will be roughly 50%-50%. Just wondering if anyone has a way to help me explain this to them. But until then I will put my pocket A's against their 2's all day long...lol.
