When you range over an array, the second variable will be a copy of the value. So when you're modifying it, you don't actually modify the value stored in the array.

You need to use the index:

for i := range *players {
        for _,tp := range *tournamentPlayers{
            if players[i].Id==tp.PlayerId {
                players[i].Points += tp.Prize

            }
        }
    }

You'll find more informations in the spec.
