You are absolutely right, I've heard of a similar story though this is a bit worser than yours, the man was said to have won a huge sum of money while playing in a physical casino, instead of keeping this a secret, cashing out the money and quietly leaving the scene for this safety, he instead out of overwhelming joy threw a party in the casino  immediately and was buying drinks for almost everyone who cared to accept the drink from him, he celebrated and got alot of congratulations from different people he never knew or meet before.

When the whole jubilation was over, the man after cashing out the money decided to leave for him, unknown to him that some group of people have laid ambush waiting for him, immediately he came by, they stopped him, shoot him in the led, collected the money and ran away, that was how he lost both the money and his leg.. This is a good example of how dangerous gambling physically can be.
