Well, gambling sounds like STS (unless they intentionally lose, in this case it's STO).
I am not so sure it is STO, I would rather say winning is more STO in a way in relation to your opponents(but depends from person to person) if your winning in a way affects person to not play anymore that game. Because if you let the person win it egoism and greed will only grow stronger and he will only play more. But your winning is STS if you did not have intention to learn that person something and you kept the prize for selfish purposes. But if a person is desperate for money(broke) in some way losing could help that person if it is a honest and nice person. It also depends on other players but if playing against house I find it utterly naive because almost every time house wins because it is all rigged, so I am not sure that many people do not realize that but their wishful thinking is so big that it shuts out their reason. Something very peculiar for me.
