It's like the Nigerian Prince tell people they can obtain a cheque worth $10,000,0000 but they have to pay an international banking fee of $1000.
Of course the question you should ask him was how much did he even deposit to win such amount of money. I believe he must have been carried away with the 'Free Deposit' that he can then win big thinking that its the way things work of course it does not because there are reputable gambling sites that which he can deposit and win which even have legit faucet that he can claim to start his gambling escapades. However, you would have made your statement without mentioning any nationality because crime and fraudulent activities is not domiciled to a particular country or race.
