Exactly! Mathematics will somehow help a little but depends on what kind of game you are playing but overall winning in gambling is just a pure luck for me. If its not your day then you'll lose no matter how good your cards or your position in game.
What you are posting here is totally contradicting. At first you are stating that math might sometimes help a little but you are also stating that it is just pure luck. Thats totally contradicting, if you have no idea then you shouldnt be saying anything at all. It doesnt has to be your day as well because most people will just lose every single day regardless
