The win percentage is determined based on all games played in the Ranked season. It is a percentage value calculated from the ratio of wins to losses.

More games played in the Ranked season mean more fluctuations in your win percentage. Therefore, a player with fewer total games played may have a higher win percentage than you.

For example! If you have played 10 games, winning 7 and losing 3, your win percentage will be 70%, compared to a player who has played 5 games without a loss, who will have a 100% win rate.
