Every player has different preferences when it comes to gambling. Some may feel the same way as you but some may not. After all, what matters is the enjoyment that a player gets when playing and the fact that the player gains something from doing it. And yes, I agree that regardless of gambling techniques players do, sometimes luck may become hindrance.
Two factors on which people make a choice between playing slots or dice. This is a pleasure and an opportunity to earn money. I am sure that most players make choices based on their ability to make money in these games.
Therefore, every gambling game will be good if the user is able to make the best use of every opportunity, so the difference about which gambling game is best depends on the user or gambler himself, because even if someone has skills in a gambling game but there will be it's time for them to get bad luck, so the incident will at least make them say this gambling game is not good on that day and will do another gambling in the hope of a greater chance of winning.
