It seems to me that one of the reasons for the different attitudes towards gambling is the informational impact. When the news shows cases of winning large sums of money in casinos, many people begin to believe that gambling is an easy way to make money. But in fact, the chance to win at the casino is very small, and most players lose money.
The advertising of gambling organizations is also affected. When bright casino advertisements with promises of quick wins are shown on TV or the Internet, people may start to think that this is really the case. But in fact, most players lose and then regret their choice.
In general, I think that society's attitude towards gambling depends on people's awareness and personal experience. If a person has played in a casino and lost a lot of money, they are likely to treat gambling negatively. And if someone has had a successful experience, then they may consider gambling just a form of entertainment.
