When gambling what do you measure? Luck or chances?
Measuring “luck” in casino games is meaningless. Otherwise you wouldn't gamble? In the long run there is no luck, so you will lose money. And in the short term the results are random, so you won't be able to measure anything.
I believe people who gamble on sports may understand this better since sometimes in sports betting some gambler's prefer to go for the smaller odds that usually have a higher winning chance and sometimes they can still end up a losing game however some prefer to go for the big game with big odds and smaller winning chances.
What's usually your pick as a gambler since sometimes some persons are luckier than others?
Sports betting is a skill game, and there it can be “measured”.
From this thread, as from another one I just replied to, I gather that most people don't understand how gambling works in general, even if they have some idea of concepts like HE, for example.
