How important is it for a good gambler mostly on sports betting, to learn to always watch replays and highlights of the general matches played previously, inorder to best know how to make a proper guess/prediction on the best team to win?
Same applies for casino Gamblers, how important is it for a potential winning gambler to learn to analyze previous games and history of results to best position and strategize oneself to win bountifully?
I don't understand what you mean? Let's say you are playing games like roulette, do you mean to check the previous results? No offense but you should know that this is luck base games and you can't find any pattern except randomness.
As for sports bettors, doesn't make sense at all as well, if you have followed that sports very well, you don't need to watch reply as for sure you know how each team wins and lost and you might put it in your memory.
