Don't dream too much of getting big wins; only think of gambling as fun. We will not be so eager to chase that win by thinking like that and the best thing is that we can manage our money to gamble and enjoy the moment of playing gambling.
That's how it should be but many gamblers are not treating gambling as a way to entertain themselves. We all want to gain huge but gambling is not the answer to achieve that because of the high risk. If some gamblers are lucky to hit a huge jackpot, other gamblers are losing their money and some of these are desperate to accumulate funds to sustain their gambling activity just like the story in the op.
If we gamble we need to accept the result, never chase your losses and quit as early as you can. Because if you became addicted it would be hard already to stop. So keep in mind to only gamble in moderation to avoid the negative effect of gambling.
Many gamblers want to get big wins but don't understand that in gambling, we have to have luck to win. And as it turns out, many of them lose and can't recover their losses and if they keep trying, they have more chances to lose a lot of money.
And when it gets out of control, they will get angry and finally think they should continue gambling again. It will not provide good results for them but will provide more losses. We shouldn't be like that, especially if we are little gamblers or just gamblers who just want to win. We can try to find other ways to make money.
