I estimated the odds, I did not say I would take a bet. There is a large difference.
I don't think there should be a difference. In practice the friction of actually making the bet is generally too high to bother, but in principle if you're giving odds you should be willing to make a small bet at (slightly better than) those odds.
I'm interested in discussing this with someone, non-publicly. It's safe to know about personally, but it's not something I'd like people in general to know.
I'm really not sure if there is a protocol for this sort of thing.
