However, in some cases, those who are experienced and can do good research have a higher winning margin.
I do not believe experience and research improve success rates in gambling. If experience is defined as how long someone has been gambling, I will state that winning at gambling is not determined by who started first. The person I taught how to place bets won millions before me. I am sure there are many such cases. Thus, experience does not guarantee success in gambling.
In terms of research, there is still no guarantee that in-depth research will result in success as long as gambling is concerned. Research is based on available statistics, but when it comes to gambling, some factors cannot be predicted, which influences the outcome of the game. This explains why gambling is widely regarded as a game of luck.
However, if a gambler can conduct research on a few games, he or she has a good chance of profiting in the long run. Choosing only the best available games and researching them can increase the depth of the research because the games are fewer in number than when a gambler researches a large number of games. For example, if a gambler researches 30 games, he is almost certain to lose, regardless of how many hours he spends researching. This is because the larger the accumulator, the greater the risk.
