Some gamblers are just lazy that is why the avoid poker games including myself i dont play poker and i dont intend to learn it any time sion, reasons being that to win piker games you must have some level of skills in the game, unlike in sports bet and slot as mentioned where gamblers can just speculate the games and trying their lucks.
This skill demanding is the reason why most people avoid poker games, and go for other casinos game's.
Understandable! It's possible to earn millions and live a lavish life if you are good at poker, but only a few can master the art of bluffing and reading other people effectively which is why it's not really a reliable profession.
However, sportsbetting also requires some degree of skill along with luck and is not entirely luck based like casino games such as slots.
