I think effect of positive gambling is determined by various factors such as the amount of money won, the frequency of winning, the individual's psychological state, the social and economic benefits of the winnings, and the overall impact on the individual's life. For some people, gambling can be a source of entertainment and a fun way to pass the time, while for others it can lead to addiction, financial loss, and negative consequences. The ability to manage one's gambling habits and the extent of the impact on one's life ultimately determines the effect of positive gambling.
