Gambling as entertainment for those who are able to control their emotions and are responsible with their bankroll, and another with a small percentage.
Gambling becomes dangerous when people continue to chase losses until they become severely addicted, leading to financial ruin and ultimately depression and mental illness.
You can entertain simply by playing games on your computers and don't lose any money at all. There are many ways of entertainment, either offline or online, free or paid, so you must be responsible with your money and financial status.
If you don't have good finance, are not rich, finding fun with gambling is quite risky for your financial status and can destroy your life. It's very unreasonable to choose bets as entertainment while it is costly, and especially when you have many alternative free options to achieve it. It's kind of personal choice but it must start with knowledge before they can change their attitude and practice to better one.
Gambling is funny and it can be so helpful for relax but only if your bets won't destroy your finance and life.
