Yes, I believe in that and I avoid betting in most sports events because I find no value in those. I only bet on the games where I'm pretty sure that chance of winning is higher for me. I never bet on those games where it only would work for me based on my luck and no analysis. So it's better to avoid betting on such games and only bet on the games where you're sure that chance of winning is higher.
You speak as those there were ever a game that's not dependent on luck but solely on your skills, knowledge and experience. Every game I know, as long as it has to do with gambling is based on luck, I'm not saying that a gamblers expertise are not required, I'm simply of the opinion that, while a gambler's skills and expertise to analyze the game effectively os also very important, i strongly believe that luck is the principal thing there. Because regardless of how good you are with your predictions or your analytical skills, the fact still remains that you may never be able to accurately predict the future, hence you need luck to make your predictions accurate and for you to win.
There’s really no such game that depends 100% on skills since even poker games sometimes depends on luck if you and your opponent manage to have an early all-in while some game you win the first 4 card then you lose the final outcome due to the river card which involves luck already.
I think he meant about betting only on games that he has high confidence that he will win due to the familiarity on the bet. It’s possible if you have a grasp on the team skills while they are against an opponent that has a clearly weaker skills.
I’m doing this strategy too since I’m not a frequent bettor on sports betting. I just place a bet on matches that I have high confidence that will win.
