In my case, I make it hard for people to guess if I lose or win. I don't want to bother them if I lose, and I don't want people asking for a share if I win. It's hard to do this, but practice makes perfect.
How about you what's your position?
I am in the same situation as you, where I don't let the people know whether I won or lost by gambling. Even in my case, it's a little different because the people around me don't know that I gamble sometimes. And I think that's better.
Because the more you tell people about your financial activities, the less privacy you have. Even if we are aware of the various news, there are many news stories where people who won jackpots through gambling were killed by kidnappers for the money. So it is always better to hide your gambling activity whether you lost or win.
