Gambling should be considered as entertainment, but gambling should not be used as a means of earning money. Those who have taken gambling as a means of earning money have become addicted to gambling and have destroyed themselves/their families. Not only from the stories of Yudhishthi in India, I have seen many people who have destroyed themselves by gambling, not only themselves but also their families. Therefore, instead of considering gambling as a means of earning money, we should consider gambling as entertainment. If gambling is considered as entertainment, then it will be possible to enjoy gambling, besides gambling will push a person towards destruction.
If a gambler plays slots to make money, then yes, it's a road to nowhere. However, this does not mean that a gambler can not earn on the gambling platform in other ways. For example, participating in leaderboards with the right strategy can generate income. Alternatively, if a casino offers a token, it's possible to earn passive income by staking it.
