Well since they are gambling responsibly without getting addicted or borrowing money is fine. Honestly, I would boldly said that they are doing well because not all gamblers that can easily do this without getting addicted to gambling. However, just like they always said that gambling is a personal decision that is the real truth about it because as a gambler that knows what gambling is all about would always gamble responsibly because there is no amount of advice that can easily change a gambler if them didn't decide by themselves.
Gambling isn't inspiring people to work hard instead it's inspiring people to be too focused on getting quick money and wanting to make money without working hard. Gambling gives you money that you'll want to spend anyhow you want because you didn't stress yourself to get the money. Gambling isn't bad but people are using it in a negative way and this is making them now thinking that gambling is a negative thing to do. With appropriate planning and mastering the act of controlling our emotions, we won't have issues gambling. You can be gambling but not make your mind to think it's free money so that you can plan the profits you made so well that it becomes an addition to your other source of income.
