Often times throughout the course of a year, users will be outbid by $1 by their commissioner. We can ensure you that they lucked out more than anything and didn't have access to seeing anyone else's bids.
Only you and any co-owners you have can see your FAAB bids or waiver claims.
Your commissioner does not have any access to your claims or who you are bidding on. They cannot see how much you have bid on any player.
