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.
I think all things has involved a luck but maybe some has less reliance on it. Gambling on the other hand seem to have more reliance on luck because why will it be called as gambling in the first place anyway? But that is true and we proved that already.
Apart from luck, gambling can involve other elements too, so if you win, we can't always say that it is because we are only lucky but that is more proudful, right? Knowing that we did our best. It is more rewarding. Winning a slight huge amount in a short period of time can seem that we beat the house already but I think not yet until we successfully cash out and spend or keep the money else where that it can't be returned again and lose in the casino.
