I think if the point is that gamblers invest a certain amount that they can afford to lose in regular gambling and hope that one day in the future they will hit the jackpot and all their previous losses will be recovered, then I think they can do it there. Because that's what most people are think about.
However, what we need to keep in mind is that we should not gamble beyond our ability to lose, which will destroy us financially.
In the end, a gambler is not pleased with losing, regardless of whether they wager with money they can afford to lose or not. His likely anger most times comes from the potential outcome. Most gamblers do not see their stake as much as the amount they hope to win, and when they do not win, they lament their loss, and the amount they hoped to win is the amount they tell people that they lost.
For example, suppose a gambler stakes $100 with the potential outcome of $1500 and loses. He is upset because he lost $1500 rather than $100, and he will most likely claim that he lost $1500 instead of $100 to make it appear that the stake was $1500. This is why, no matter how small a gambler's stake, he will feel bad if he loses.
