You note that nowhere in your YC application do they specifically ask you about money stuff.
But, you talked to some YC Alums before the interview and they all asked you about $.
And since you didn't get selected you now assume that the YC partners really only care about the $? Sorry, I think that's a leap in thinking that might be in the wrong direction.
I applied with a website that let people name & share color... There wasn't billion dollar company sitting in front of them. There were a few guys with a passionate community and the ability to build great product. We were never asked in our interview about $ and didn't need to bullshit anything.
Yes, the Valley hype scene is heavily influenced by who's the next billion dollar company and puts little success on people making $5-10M/year in great businesses... But that isn't YC.
PG has on a number of occasions given me advice that is all about us as the founders being happy. Not about YC getting the biggest return possible.
So yeah, hopefully your idea could be a big business. But I would argue the opposite of what your post says. YC mostly cares that your idea is big and that you are a team that might be able to pull it off.
And IMHO... Try not to bullshit. It'll eventually catch up to you.
