Sportsbook gambling isn’t completely focused on luck, it does give room for those who know the game or sports to predict just what’s to expect as possible outcomes of a game. You have historical data as per head to head, the grounds on which the game would be played, winning streak, what’s happening on the table, fixtures ahead, what league is the teams participating in and many more. All these statistics helps you to make better predictions and brings you closely to luck and wins.
Everything in life has luck factor and with sports, gambling the weight of luck factor is bigger than in other things. I agree that in sports, you can use available data, head to head records and possible available human resources (called players) for the match, or fitness status of athletes in order to make your bet decision.
It's good to analyze all of these based on data and make your decisions like data-driven, but there is luck factor and unexpected, unpredictable things will happen that can make your bet as a lost one. It includes manipulations from sportbookers or dark networks in gambling industry that you don't know and can not control.
With gambling in general and sports betting in particular, let's bet responsibibly. Avoid to be over confident and bet all money you have in any match.
