I think that avoiding friends when they get a big win is really a fact that often happens, and I think there are several factors that are the reason why they prefer to hide it rather than tell other people especially their friends, one of the reasons is obviously that they don't want to share part of their winnings with others even if the other person doesn't ask, but they always feel worried that other people who know about it will ask for a share especially if they are one of their friends, which means they are clearly someone who has a fairly stingy personality.
And the other reason might be that they really need the money for something, like buying something important for their life, or saving money or whatever, and actually I admit that the winnings are entirely your right and it's up to you to share some of it with others to party or to celebrate your winnings or not at all, all the choices are yours, But what I would suggest is that if you don't want to share any of your winnings with anyone then it's definitely better to keep it hidden and never tell anyone about it, because usually if you do tell and your friends want a share but you don't give it to them then it can cause problems in the relationship.
When ever someone people make a big win they start avoiding there friends and it is a common thing among gamblers greed giving out money is something is very difficult for them. They have this mentality that they took the risk them self and there is nothing to give out but that is a very bad mentality. And that is something that is common among guys. And I don't see anything wrong with given out money. The money might get finished and you will end up going back to your friends just give out an equal amount to them and put a smile on there face.
Buying something important with money from gambling. True doh but it is still not an excuse you can tell them and they will definitely understand. An not even share everything but given the little you can give is not baf at all. I don't know for others but its a thing of joy to me to always give because when you die you are not going anywhere with anything. For does that have such mindset should reconsider. And have a change of mind.
Yes and I think if someone hides their winnings from other people then there won't be any problems, because the problem is usually like I said above, when someone tells other people that they have won but they don't want to share anything at all. to other people, especially some of my gambling friends, this can usually cause problems between friendships, and to be honest, for myself, I usually only tell about my winnings to one of my real friends who is really good to me, where I always share some of the winnings if I wins and vice versa he also does the same action when he wins, and this is a scenario that I think is useful where you help each other when you don't have money to gamble.
The point is that it's better not to tell them if you don't want to share any of the winnings you get even though basically for example they don't ask for a share, but sometimes I like to feel bad if I don't give them the opportunity to taste the money I won, and for me personally, I usually prefer to tell one of my real friends because he also often gives me a share if he manages to win.
