Actually, no, that wallet address is the BET address. It represents the bet that you made. That's why it serves as the Bet ID -- because each one is unique. Take a look at this as an example:

Oh man. This entire time you've been looking at the wrong BTC address.  

The only thing fishy is that your archive says "Confirmed" instead of "Paid," but its impossible to know if it was actually paid out or not because you don't have evidence of the payout address...
