It can go on for 5 years or more and don't think it can't, where the card that comes after the money goes in, turn or river, is the worst card that can possibley come for your hand so regularly that you can just call the card out loud with confidence. Not because you are psychic, but because the worst card possible is coming and you know what the worst card possible is (usually).
(The 5 years cited is admittedly from part-time play and translates to about 1 year of full-time play.)
So no hand or even series of hands is a surprise, or unbelievable, or unexpected, but only this "got stuck for tens of thousands of hands" thing is. It's actually more about your relationship to your life and the universe than it is about rote odds. The deck is part of the quanta. And "it" knows all (not the deck, the quantum field).
Hope that clears things up and helps.
