If there are infinity universes, doesn't that mean that if there is any probability at all of something happening, it will happen an infinite number of times?

Speaking purely theoretically, if there are, in fact, infinity universes (and not just A LOT of them), then if there is any probability at all that something will happen, then it will happen, and it will happen an infinite number of times. Again, this is ONLY if there are infinity universes, which is not a proven concept, and which is a concept that our brains cannot wrap themselves around (as infinity is so abstract). But, yes, speaking purely from a probability statistics point-of-view, everything will happen infinity times.
