It just has to happen and there isn't anyway you can teach it because it's your own luck and not that of anyone else. The way anyone that isn't you is going to benefit is when they're copying your bets and following it according as you're doing. Copying someone is dangerous on its own but when you're sure the individual that you're copying is a professional, you won't be that nervous. Everything is depending on luck when gambling hence I don't stress myself to get the attention of people that wants to learn how to gamble because I'm still learning and haven't perfected it. Nobody can teach you how to gamble while being safe always that you aren't risking money. When gambling you need money to make more money.
You can actually teach your strategy to someone. For example trading is a skill that highly depends on getting the prediction right, every trader has their own strategy they use in getting profits no matter how little it may be and basically it can be thought. Same way it is in gambling, every bettor has a unique way of getting luck to win after predicting. And yeah, it can also be passed down from one person to another. They may not necessarily get it right just the way you do but there will be an upgrade in the way analyze their bet.
Gambling and Trading both involves applying strategy and also prediction, and it's also possible to experienced individuals to also share their experiences and approach with others. While it's quite true that each individual needs to modify and tailor the strategy to suit their own personal position or situation, it's also worth noting that their chances of success can be drastically increased if they have a solid foundation, and I think that's just about one of the most important thing.
