This should not be done because it will just jeopardize the life of the gambler. But I guess there are those who are too proud about their winnings which is why they cannot suppress their excitement to share it. You will have to be careful with those guys that went to the house of the gambler, OP. There's a chance they will do something wrong and some of you will be dragged by his mistake.
There are some gamblers who want to tell others about their wins. They feel proud because of telling others. Such people cannot hide many things even if they want to, this creates a big problem for them. Because whatever they do in a simple mind is not simple for others. Some are waiting and they will take advantage of the opportunity and do that criminal act. No matter how simple or simple the gambler is, he must emphasize on his safety. Those who do not give importance to this matter will face unpleasant incidents later.
