If there are indeed an infinite, and not just very large, number of
universes and if the probability of your keyboard turning into a teapot is
greater than zero (and it is) then what you say is incorrect, there is an
equal number of both things happening.

Quite true, and that is why I said standard probability theory is not of
much use in dealing with infinite sets.

The problem is that there are an infinite number of subsets that are just as
large as the entire set, in fact, that is the very mathematical definition
of infinity.
