That statement is (sort of) true, but what a lot of scientists think is true doesn't say much about what is actually true.
That statement is not sort of true, and its not a matter of lack of proof, or trusting what scientists say. 'Infinite number of universes' does not imply that any of them are anime universes. There are an infinite number of irrational numbers, and none of them are rational numbers. If there are an infinite number of stars in the universe, none of them are tacos. If there are an infinite number of worlds in a 'many worlds' type multi-verse, none of them are populated by cartoon characters behaving in impossibly stylized ways.

I speculate that there must be some sense in which impossibilities do have some kind of subtle quasi-reality which can somehow influence an actual, existing reality. But that sort of thing is well outside of even the speculative multi-verse of string theorists, which itself is well, well beyond the "many worlds" multi-verse related to decoherence.
