Research creates an edge towards other gamblers, but it does not guarantee sure winning, although it increases the potentials of winning. Luck is still the key element in gambling. There are a lot of good researchers out there who gamble and often end up losing, compared to those who just got luck and decide to gamble, and end up winning it all. However, taking research should still be encourage most particularly for sports betting, at least you got to reduce your chances of losing.
In my opinion it is a useless and superfluous thing and i explain to you the reason: in my opinion it is necessary to think and understand that much happens because of luck
In example yesterday my partner commented that he would never expect that in Serie A the Como would win on Napoli.
He lost his bet, even if he had done good research.
