People say we have to put in some effort to study a certain game before placing a bet. By study, they mean using different resources, checking the news, trends, rumors, and so on, because those are all important factors when capping games.
If we do all of that, it really means we're not being lazy.
But does doing all that really increase our chances of winning, or more specifically, make us profitable?
I think this really depends on the type of gambling you are playing in the first place.
Since you mentioned about
checking the news, rumors, resources, etc.., I believe you are pertaining about sports-betting if I am correct? You mentioned about external factors that can affect a player or a person in sports-betting since these factors are only relevant in this type of gambling.
On the other hand, the factors that you just mentioned cannot apply to traditional card game gambling since they are irrelevant and immaterial. Regardless of those factors, card games are unaffected because they rely mostly on luck. Despite all the research that a person may make, the results would be unaffected as LUCK plays a majority role in this type of gambling.
In conclusion, luck plays a crucial role in gambling regardless of whether it may involve sports-betting or not. It has nothing to do with the laziness of a person or their effort in doing their respective research.
