l'effectif non, mais le résultat oui.
Elo Rating SystemThe aim of the system is simple. After each game, rating points are exchanged between the teams depending on the result. Whatever the home team gains in Elo, the away team will lose the exact same value of Elo (or vice versa). If the home team gains 20 Elo points, the away team will lose 20 Elo points.
The difference in ratings between the two teams serves as a predictor for the outcome of a match. Each team’s Elo rating will update on a game-by-game basis based on the likelihood of each team winning and the actual outcome of the match. In simple terms, the following tends to happen:

If the higher-rated team wins, fewer points will be exchanged.

If the lower-rated team unexpectedly wins, more points will be exchanged.

If the match ends in a draw, the lower-rated team will gain a few points.

The greater the margin of victory, the greater the number of points exchanged is.
Remember whatever one team gains, the other team loses!
Over the long-term, the Elo rating system is self-correcting. A team will gain or lose points relative to their corresponding Elo rating until the ratings reflect their true strength. If a team is undervalued, they will gain more points in each game until their strength is accurately represented by the system.
