Sports betting systems are a set of events that when combined for a specific game for a specific sport, represent a profitable betting scenario. Sportsbooks tend to use these systems in their analysis to provide more accurate odds for games in each sport. But, it is known that novice players get caught up in the illusion that using a system will work. However, it's fairly likely that the people creating the odds will have adjusted the system so that it cannot be used for a profitable purpose.
