The major reason I believe gambling comes with luck not strategy is because few new gamblers also win with their first game. Strategy or skill is not necessarily since a person can predict, sometimes we even predict with zero hope of winning but at the end we get surprised winning.
I even hear some gamblers complaining about games they put their all and hope but never get to win, if there’s anything associated with skill when gambling I wonder what kind of skill is that or are they always referring to their favorite team when placing a bet. I have seen people share their strategy here but that doesn’t mean strategy works always rather anyone can be lucky and still lose at times that’s gambling for everyone.
I have heard someone who first played gambling they could immediately get a big win and even I have seen it myself when my friend won from their first gambling, and they even won using a welcome bonus. Before playing he asked how to play it because it was the first time, that's why I believe that this is not a strategy or skill, because when they are lucky they will be able to win even though they are new users.
But you have to be careful with this, sometimes this is one of the factors that makes them addicted to gambling. Those who are new to gambling and win immediately will have the wrong mindset, because they usually think that if they deposit more and bet bigger, then they will win bigger too. they don't know that this is a matter of luck.
