Yes, I completely agree with the OP. Even if you wanted to show off to your friends, relatives or other people, they will probably think about the game and they will definitely have an irresistible desire to play. They will do this with thoughts like “why am I worse than him or other winning players” or they just want to test their luck. And even if the player starts to lose, he will bet more and more furiously with each bet, trying to make the winnings higher than you told him. Behind these stupid actions will be human envy, depression, anger that a person has accumulated, whether at work or anywhere else.
The main thing I want to say is that even when telling someone about our victories, we seem to invite the person to play, but at this moment we don’t realize it, because we just want to show ourselves higher, increase our worth, or just show off like a little boy, and not an adult and reasonable person.
I don't see the need to show off in the first place. I don't actually know why people do that because my definition of wealth is that it should be used to help humanity and not oppress them. Flaunting one's wealth is actually oppressive and I do not subscribe to that in any way whatsoever.
Looking at it from another perspective, how you go about with the publicity of your winning depends on your safety. If you are from a neighborhood where disclosing your finances will pose a security threat to you, then there will be no need letting anyone know you have a winning. On the other hand, if such publicity does not generate any form of security threat, then there shouldn't be any problem with sharing with friends and associates. However, in my own case, I love my privacy so all information about my gambling stays with me.
