No.
What I was saying is that while the probability in an infinite timeline of anything happening is 1 (I agree with you), it does not mean that all things possible all exist at the same time. Even on an infinite timeline, there is still a past, present, and future, and things can exist before other things and after others without any overlap. IE humans never existed with dinosaurs.
Also, as the probability in an infinite universe of me existing is 1, that does not mean there's an exact copy of me somewhere else in the universe. It just means that I exist, it doesn't mean there's two of me.
EDIT: I retract my second statement after rereading it (it's highlighted).
