It depends on how good the strategy you have/use, if for example you have a good strategy to use in the right place then it can help increase your chances of getting closer to victory, but when you apply the strategy in the wrong place such as applying the strategy to a type of game that is purely based on luck then it will not change anything or will not affect the results at all, sometimes I often see gamblers especially some of my friends who apply strategies to types of games of chance such as casino games and it is only natural that the results are still disappointing.
On the other hand, strategy actually has an effect that can increase a person's hopes and beliefs, I'm sure anyone will agree with this, many of them become very enthusiastic waiting for the results, and when it turns out the results are not as expected then usually they will be emotional (I'm talking about gamblers who come with the intention of making a lot of money), and that emotion is what leads gamblers to a much worse situation, so instill in your mind that strategy is nothing more than a tool.
Strategies will really be that relevant on the time that you are dealing with games on which they are really that requiring up some strategies so that you could be having some upperhand but these things will be irrelevant when dealing up with casino games and this is why it will be basing up on the things that you are dealing with on which to see whether it is applicable or having no sense on making use into. Strategies are good when you do really want to enjoy up the game at least but just like on what everyone is saying on here that there's no assurance that you will be able to win up the game or proof that it is making things for you to be able to easy to win.
It can really affect someones hopes and beliefs at the moment that you do make out some betting. This will be only that good when dealing with sports betting or some card games but cant be removed that luck factor will be mainly needed when it comes into this aspect. This is why its important that you do make out those kind of realizations at least so that you wont be that becoming desperate on doing gambling. Most gamblers will really be that too hopeful on things and thats why on the time that they do gambling whether casino based or betting type then they will be trying out to apply some strategies and setting high hopes with it which is really very wrong.
