Many people have committed suicide due to gambling depression, not because they feel pressured by gambling, but because they can't control themselves due to excessive losses.
Perhaps suicide will help them overcome the depression or debt they experience, as people who gamble to the point of suicide often gamble with other people's money.
These individuals are usually quiet and don't share much with others, making it difficult to get help.
It is their responsibility as they must know that gambling is risky if they bet irresonponsibly. All casinos have warnings, reminders about Responsible Gambling and even without those messages, careful people must organize their finance well enough in order to assign small part of their fund for risky things including gambling.
If someone destroys their finance by bets, it's their responsibility and it's not responsibility of either the gambling industry, the casino or the game provider. Generally, risky activities in finance are only deserved to be assigned with smallest part of an individual finance.
I agree with @OcTradism that it's true that responsibility for gambling rests entirely with the individual. When choosing to gamble, you're making a conscious decision that your actions have consequences. Therefore, it's natural that the results, whether good or bad, must be borne by the individual.
From my perspective (each person may have a different perspective), this is also closely related to how a person prioritizes life. Just as someone might spend their money on luxury goods, excessive socializing, or even a consumptive lifestyle, all of these are perfectly acceptable as long as the portion is small and doesn't interfere with meeting basic needs.
The difference with gambling is simply the form of activity. Therefore, in my opinion, the core issue isn't whether there are casinos or other entertainment providers, but rather how well a person can control themselves and manage their personal enjoyment or entertainment within a reasonable or acceptable range.
Therefore, I believe that if someone is able to view gambling as a form of supplemental entertainment, not a source of income or a shortcut to wealth, the risks and consequences that arise will certainly be manageable. Because indeed, for me personally, financial management is a reflection of personal discipline and self-awareness, which is not the responsibility of other people, not even the responsibility of the provider or casino where you play.
