Your intuition is correct here. OP is wrong. An infinite set of branches of the wavefunction does not necessarily imply that everything you can imagine must happen somewhere in that wavefunction.
But surely the chance of "me" winning the lottery at least once is 1 if I play an infinite number of times
I think that’s only true if the lottery numbers you end up with are truly the result of random selection in infinite universes.

Is the lottery not random?
I think it’s one of those “probably close enough to random” type things. I found this: https://quantumbase.com/sse/lottery/
