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.
