If you are gambling with you husband's money and have won a big jackpot then it is most likely that your husband would be happy if you tell him about it. If your family is not financially very well off and you are gambling with your husband's hard earned money and making a big loss then it may ruin your marital life.
In my opinion, this depends on how someone evaluates gambling itself. If someone thinks gambling is something bad, then even if they hear the news of a win they probably won't be happy with it.
However, if someone can accept gambling then the response we will see is as you said. If they hear news of victory they will be happy and conversely if they hear news of defeat they will not be happy.
The reason is that we cannot deny that not everyone accepts gambling.
