I guess the wallet address (14U3v66uuFzVzgaRrvhfcn5pSSxZwRbEff) is not related to any exchange/gambling sites/services base on walletexplorer.com
And the owner of this wallet is only a person since based on the block explorer his transaction was sent out to 999dice.com and poloniex.com. So should forget about this and move forward, serve this as a lesson, if possible make sure you double check and even tripled check the receiving address by looking the 5 character at the beginning and at the end.
