If I subscribe to the many worlds theory, every time I buy a lottery ticket one of me wins.

But what evidence is there for this being true?

Umm...logic? Statistics? If something has a chance of happening, even the smallest possible chance conceivable, it will happen given infinite time and iteration.

Well, but if there are other “me”s, then there must be some set of common events that must occur in each universe containing a copy of me in order for that individual to qualify as me. In that case, isn’t it entirely possible that those particular things that must be in place preclude certain other possibilities that make it such that there is no chance that some otherwise conceivable events could occur?

Sure, and that would fall under "can't happen, won't happen".

And if we're getting that philosophical about it, what qualifies as "you"? Arguably, that's just you, since you represent a single culmination of events and possibilities. All other variations would technically be someone else with a mostly similar history. You could consider a "spectrum" of you's, but again, where is the cutoff? Trying to define that gets pretty tricky.

I agree with all of that. But the bigger point is that there are things that can’t/won’t happen that we can’t predict, so this means we can’t assume that “there must be a universe in which X happens to me”.

In respect to the lottery, every (lottery valid) combination has a chance of happening and we are assuming infinite variation, so if someone buys a lotto ticket for say "1 2 3 4 5", that will be the picked numbers in at least one variation.

Ok, that makes sense. I would agree that for any truly random circumstance, when given infinite iterations, all possible combinations will eventually occur.
