Depending on gambling in the first place is never a good thing. Betting some would be fine as long as you can bear losing. No matter what game you engage yourself with, whether cardgame, dice game, sportsbetting and such; winning won't be certain. So choose what would give you enjoyment atleast, 'coz that would make your bets more worthy. What makes gambling bad in the first place is gambler's assumption of getting rich in an instant. This is more likely because of stories wherein players have earned huge reward from playing, without considering how much that player have lost during the 'run'. Everything would be based from luck or one's fate.
No one is immune from gambling as long as they have a hobby in sports, but to what extent can people be responsible for the gambling decisions they choose? This is what you have to avoid, namely the mindset of getting rich quick without working smart at all like the fairy tales that we often hear behind the success of people at gambling. More precisely people can't avoid gambling if they don't want to, there is one piece of advice that I often hear "Habit will lead you to addiction".
Therefore avoid irresponsible gambling, gamble only when you can afford to lose money and avoid interpreting gambling very close to wealth. In fact, getting rich does not happen because relying solely on luck and engaging in gambling using small amounts of money will not make people richer either.
