Officially, Esports is short for electronic sports and refers to competitive video gaming with tournament and league structures just like traditional sports. In Esports, gamers square off either in teams (multiplayer) or individually.
Professional esports players spend more than 8 hours a day practicing their skills alone and spend another 6-8 hours playing with their team. Most teams have regular scrims, which is professional teams playing against each other outside of any competitive organization to train and develop new strategies.
