Gambling for fun and gambling with the intentions to make much money are not the same. People who think that gambling has a certain strategy are those that want to make a living from gambling. Gambling is a fun thing and nothing more.
There are gambling strategies actually working perfectly for some people but not a must that we use same strategies others are using for our own, everyone has to think about what's best for them and adopt using any strategy they think is best for themselves, we should also be reminded that gambling takes risk, despite the more we get involved in it doesn't mean we must alwa win or loose in whenever we gambling because the main focus was to have fun.
There is no strategy that working perfectly, if it does exist means that there are some people who become billionaire by using the strategy.
If you say strategies are working perfectly means that it will never failed and it should be able to be used by all gamblers.
However I think you want to say that there are some gamblers who win some money by using specific strategy but it does not mean that the strategy is working perfectly because these gamblers may lose their money as well using the same strategy.
Well, it cant really be just avoided for you not to mind on that you would be having some advantages on making use of these strategies which it is really that something a normal or common approach.
Just go with the flow and make use of strategies on making your capital to sustain for longer duration or time spent on gambling if you are really that looking or finding for leisure.
If you are really that looking for that thing then you wont really be making yourself that desperate.
