In simple terms, gambling will always be associated with luck. It’s an inseparable as it may seem. It’s a valid reason that you win because you are lucky, and you lose because you aren’t lucky, that’s how simple it is. However, with sports betting, this kind of game adds skill aside from luck. But still in general, you can’t win and beat the house if you don’t have the luck and skills to make you win. Luck still makes the biggest factor to make you win from gambling.
Gambling will be worth nothing if the luck factor is not there because luck as a natural phinominum is essential to everything that we do and gambling is one of them, we shouldn't make the mistake of thinking that luck is a feature in a casino no, luck is just a natural phinominum that occurs anytime you are playing a game of chances or something that you are not sure or can't control its outcome, so that point luck becomes and important factors.
