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.
Although betting on the small odds has a higher chance of winning, it still doesn't guarantee winning. It was just the same as betting on the higher odds with a small chance of winning.
We all have to believe that gambling always needs luck to win, no matter what it is. We can't rely on our skills and experience because that won't be enough for us to get a favor.
We all just remember that no matter how long we've been gambling, luck is still what we need to win.
