Even people who gamble occasionally are not free from the pain of defeat, because sometimes we lose control when we lose in a row, but I have applied it to myself, I have to spend the budget that I have prepared or take it home twice as much, in terms of dealing with losses I will stop gambling for a while
People that gambling occasionally would have literally forgot about their previous losses before they return to gambling again. Since they can take a week or more before gambling again and during their absence, they engage in other activities which takes off their mind from the losses, they are not free of the pain of defeat but they may not face it always like the regular gamblers who gambles every day. The approach you employ in handling your losses is good, it will prevent you from gambling with emotion which can cause greed and more losses.
Indeed, just like you said they are not free in pain as they expereiced losses but since that they've got other activities they can removed those thoughts inside them and continue to work with other things that they needed to address, and once they feel to gamble again they just do the same routine, play and see if luck permits or if the outcome is just the same.
