Sports betting systems are sets of events that when combined for a particular game for a particular sport represent a profitable betting scenario.
Since sports betting involves humans, there is no deterministic edge to the house or the gambler. Systems supposedly allow the gambler to have an edge or an advantage. Sportsbooks use systems in their analysis to set more accurate odds.
Therefore, the novice gambler may believe that using a system will always work, but it is the general consensus that at some point the oddsmakers will have adjusted for the system to make it no longer profitable. Very short-lived systems are called trends. Any single event that estimates a selection to have a higher likelihood of winning is called an angle as they are meant to be used in conjunction with other angles and trends to produce systems. Any sample space can be constrained enough with meaningless criteria to create the illusion of a profitable betting system.
