Gambling becomes wrong when you're getting addicted to it. If you gamble with a certain amount like once every month or so. You should be okay.
Yes I agreed on you mate in that matter, because we know that being an addict is not a good thing to become.
So gambling is not a good habit at all.
Even you gamble with a certain amount every month, you can still be on the wrong decision. Because you have been allocating a budget to gamble, that's making it wrong. What if the time of needs come? When you have something important to buy or use that money for, for your relatives? But you did allocate a budget of it instead of that important matter. And that what makes gambling wrong.
That is why you have to allocate something for the gambling right? As long as you are balanced enough to not waste that money you have separated for own use or personal. And that is just the common dilemma for gamblers even if u said you would set it aside if you lose there is always the rage to gain or to take back what was lost to you in gambling. Generally it is wrong but it is definitely a fault in your own self righteousness.
Even though we have this control in ourselves, still we are going to lose no matter what, it is how gambling was made, it was made to make a huge bankroll out of the players bets everyday, the more players that they do have the higher the bankroll they could have in a day. The house edge is the one who is making this bankroll, the reason why we are having too many loses than winning, and the reason why we are getting addicted on it.
