? I never actually said I "believe" these things are happening.
I said it was "possible" that the momotaro thing could happen. That's it. Realize that when I talk about the future, I always use "if" "maybe" "possibly" unless I'm absolutely sure about something set up by the story.
Big Mom losing is set up by the story. I'm absolutely sure it's going to happen here. If it doesn't then it will be my first real "L" this arc because everything else has been a theory at most ("if" "maybe" "possibly") or it was something I was sure of (Zoro vs King, Sanji vs Queen, Kid vs Big Mom, etc).
For example, I "theorized" Yamato would fight Jack. It didn't happen. I didn't take an L because I never actually, wholeheartedly believed it WOULD happen. I never said the the F6 or Calamities WOULD get up. I said we can't KNOW if they can or can't get up until we see the narration end the fights, which exactly happened in 1022, 1026, 1035 and 1036.
