I’m not sure I agree on your take. There are of course different definitions of infinity which would have different rules based on said definition. But if our universe is infinite and physics as we know it remains true then we would have to run into all the variations of every molecule combination possible again and again.

Saying we won’t see any even numbers in an infinite set of odd numbers is obvious as the rules of that infinite set have been defined. There are no such rules in the universe.

The universe appears to be expanding close to e^t. If it continues to do so, each fundamental matter particle may end up isolated in a Hubble volume where the only photons from the rest of the universe have been red shifted to wavelengths larger than that Hubble volume.
