I bet no one like to lose but its part of gambling that we need to embrace. Thus if a gambler cant stand losing his/her money then its best to not gamble again since gambling is more on luck.
Last Tuesday is the lucky day for me when I play slot, its the first time I hit a bit high multiplier. I never expect to win but it really made feel that its not really about to entertain ourselves or to have fun, because we really have a chance to earn real money and that is if we are lucky.
I have to say nobody really "likes" losing, but after a while it becomes such a normal thing that you do not care about it, the difference between a small win and a small loss is really not that big. I probably give the same null reaction to winning 1k satoshi as well as losing 1k satoshi.
Of course if I end up losing a lot more, then I would be a bit sadder, or if I end up winning more then I would be happier but if you know what you are doing then you do not gamble with a lot and that is why you do not lose a lot all at once.
I know what I am about and that is why I do not gamble more than 1k satoshi per bet, which means I can't lose more than 1k satoshi per bet, which means I can't get sad about it neither. All in all, know your limits emotionally and gamble accordingly. If you emotions do not get to a level where it is too risky, then we can't really keep the control and may lose it.
