Of course.  One is a strict subset of the other.  And the multiverse is
very, very, very big.  So far I don't think you're saying anything
controversial.

Any _given_ similar-but-not-identical configuration may be vastly less
probable than ours (say, all the same as ours but that it includes a giant
space duck) but there are so many variations -- even trivial ones like
slight differences in decay times of a particular atom -- that they must
quickly overwhelm the identical ones.

You can really make the same argument for cup of coffee I think.
