Is gambling OK? Don't bet it! There's not an easy or instantly obvious proof text answer to that question.
In my own point of view, gambling is not a sin if you can control yourself when you play and if you are not an addict in gambling because when you only play, you only play on it not making it as a hobby that will come up being addicted on it. That's why it is better to limit yourself when you are playing.
I can only
give my opinion according to my way of thinking. That gamble can be said to be a sin because maybe when we play gambling we can win some money without hard work. We can get money and get wages without doing anything. That means, we can be rich people with instant and without effort at all. Therefore, people will consider gambling as
something unfair.
There is
another assumption that gambling is a waste of money and time. It can be regarded as something of a spree, and a spree is a sin. The most severe is there are people who are willing to sacrifice and distress others just for gambling. They take their parents or family's money for gambling and
harming them. However, this is just my opinion. And we should avoid all that.
