I agree and op's opinion is very real, but can you guarantee that what you said can be the key to success? because in gambling no one will win except the bookie, changing the title to "tips to increase winnings in gambling" doesn't sound too bad
You can’t guarantee being successful in gambling but you can be able to have a good gambling experience with that tips, I can just consider the tips to be a way to play safe in gambling rather than a means to win the bookie since it’s an already a known fact that we can’t win against bookies no matter how much we try and the type of strategy we try to use.
There is no shortcut to successful gambling neither is there a long way to successful gambling, gambling is a game of luck and as such experience, skills, etc doesn't guarantee successful gambling rather what experience and skills does is that, it will only help one to minimize loss by playing safely and picking options that the possibility of winning is higher because there are game we can tell 80-90% of what will happen merely looking at them but because it is a game of luck it becomes unpredictable.
I definitely agree with you success in gambling is not a function of how experienced or knowledgeable one is when it comes to gambling related activities but it's purely on the grounds of luck so when gambling people should have it at the back of their minds that matter the amount of money you spend in gambling or how careful one is with gambling you will still lose if the odds are not favouring you, this issue of gambling should be made clear to gambler's that in gambling there is no free odd to win or there is no guarantee of winning because gambling is one thing that is made for the casinos alone to benefit because looking at the winning percentage of gamblers the winning percentage is not even up to ten percent of the total people gambling and that is what makes it difficult and dangerous for people who are gambling because it's like they are moving against the odds
