Gambling = LUCK that is the reality here , if you think you can beat the house because you are knowledgeable and experienced?
then you are wrong because without luck on your site , you will go home with nothing but sadness.
I see it differently though, gambling is not particularly the game of luck, that's how I see it, and for you to believe that gambling is luck, that is the way you see it. But let me be a bit constructive about this. I see gambling as a function of luck if one wins in some categories of it, just like how it is when it comes to gambling with slots and some others. Of course, you can't just make what you know or expertise work in this area of gambling, you will always be at the mercy of luck because the slot's algorithm has been written already, you can't change it, it will just be functioning based on how it has been structured. If you are lucky to play at that time it wanted to bless gamblers, and you also played it rightly, it will, of course, bless you, and one could say they are lucky in this regard.
But in many aspects of gambling, especially sports betting, you can say otherwise, luck is not the main function here. Fine, you can be lucky still, it is possible, but mostly, you have to gain through your expertise in it and through the right speculations thereof. You have to know how to blend your game together and also know the right means that will give the best results. For this, you need beyond luck, it is not guesswork, but the work of your plan, efforts and expertise which makes it commendable, unlike in the case of luck which is not a function of how good you are.
