Hi Gamesmanager123, we appreciate you posting your concern here on our forums. When a high points player loses against low points player, he will be deducted more points in the Match. Then when lower points than him lose, the high points will receive a few points. It is based on the differences between each player's points.
For more info about the ELO system of the Match read it here in our Solution page: https://perfectswing.freshdesk.com/en/support/solutions/articles/47000777135-match-multiplayer-
