Poker Question Im Pissed OFF

[Ron_Mexico]

I was playing poker today. It was some stupid game called chicago. The pot was pretty big and the player to my right was talking my ear off. I got distracted and accidently stated that I only had a pair of AAs when in reality I had As and 5s. The other person and everyone else claimed I had to be held to the original statement of As. Is this a rule in poker? I would think the cards would speak for themselves.

It was my fault. I was playing a stupid game Im unfamiliar with and allowed myself to get disctracted, but whats the rule on this. It was a pretty big pot.
