Yes, I agree with you, everyone should take gambling as an entertaining thing not taking a reliable source of income. Responsible gambling is a thing where gamblers are able to control their emotions, set a limit and they are fully aware of the risk. Additionally, i also think chasing winning is a dangerous thing, it will make you crazy and you will end up as a gambling addict. So, i wanna say balancing entertainment with your responsible behavior can help you to avoid the pitfalls of addiction and that's how you could maintain a healthy relationship with gambling.
Everyone has their own reasons for gambling and not everyone can think of gambling as just entertainment. Most of those who come to gambling places expect to get big profits quickly with minimal capital.
Yes, before we enter the world of gambling we should be aware of the risks and the most important thing is to set limits, but i think maybe not many people can do that because it will not be easy when we are already gambling, unconsciously we will enjoy it and feel we have to spend a little more time to be able to win. We will only realize when our money has run out.
