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.
