This is the life of professional video gamers: They train for hours each day, score lucrative endorsement deals, and get flown all over the world to compete in front of fans – sometimes at sold out venues – for big cash prizes.
Top players get recruited into professionally managed teams, not unlike how Ferrari and Red Bull have Formula 1 drivers who are on the same team but still compete individually. Such is the life of a professional athlete and it's the same for top video gamers.
