The thing is whether you build a very smart and good strategy according to you the end point of gambling will still boil down to the point luck is the most important thing as it pertain to gambling so anyone who is thinking of outsmarting the role of luck by doing research and always been careful for the purpose of getting it big in gambling will be disappointed.
Gambling is luck based that is a fact that is universally acceptable and not strategy work I don't know the gambling that anyone can actually develop to outshine luck because gambling is a game of probability and probability is all about luck
In as much as you are right, it's still very much impotant we also know that different types of games in gambling come with different levels of luck, we have games that outcome is completely based on how lucky or not the player is, while we have other games where outcome is based on part knowledge and part luck, example is sports betting, your level of knowledge in sports contributes greatly to the number of bets you will win, as well as luck.
While there are other games where outcome is based your skill and luck.
So aside slot and some casino games which are completely luck based, knowledge and skill can still be used to win games, this is not outsmarting luck anyway, since luck is still needed regardless of a gambler's level of expertise.
