I was just playing Hi-Lo, making small dollar bets, if it's 5 number card I select higher card and win, if it's 10 number then I go with 'low' and win.
Then I was greeted with Ace card, minimal possibility for equal card right (i.e, Ace), so I go all in, and guess what happens, the result is Ace means I lost the bet.
Then I have all sorts of thoughts blaming casino, like do they manipulate the result of the game when user goes all in. I am sure they are all fair, it's just that the possibility of losing the game may be minimal but it's never 0.
This is the problem with most gambling in general and could distinguish it from other high risk stakes like altcoins. If you go all in and lose, often for not very great returns, you have lost your money. It also doesn't make much sense for the house to give you better than 50 / 50 odds in any betting situation, so you'll always stand a greater chance of losing and the casino a greater chance of winning. Over the long run this will wipe you out. Unless you're playing a skill based game, which has natural variance built in but your influence should sway you into profit over the long term, then you really never stand a chance and it is simply a determination of how fast you will lose your money.
