how should i access a player folder to change the players value?

i'm asking this question again but basically you push a ball and the ball falls and respawns, during the fall it hits a part which executes a script that respawns the ball, but i also want the script to increase the "wins" value

part script:

function onTouched(hit)
    if hit.Name == "Ball" then
    game.workspace.Ball:Destroy()
    local newball = Instance.new("Part", workspace)
    local face = Instance.new("Decal", newball)
    local actualface = "rbxassetid://34067417"
    newball.Shape = Enum.PartType.Ball
    newball.Size = Vector3.new(4,4,4)
    newball.Position = Vector3.new(-25.255, 4.889, 25.769)
    newball.Name = "Ball"
    newball.TopSurface = Enum.SurfaceType.Smooth
    newball.BottomSurface = Enum.SurfaceType.Smooth
    newball.Anchored = false
    face.Texture = actualface
    face.Face = Enum.NormalId.Back
    end
end
script.Parent.Touched:Connect(onTouched)

leaderboard script if anyones interested:

local datastore = game:GetService("DataStoreService")
local ds1 = datastore:GetDataStore("winsaves")

game.Players.PlayerAdded:connect(function(plr)
    local folder = Instance.new("Folder", plr)
    folder.Name = 'leaderstats'
    local wins = Instance.new("IntValue", folder)
    wins.Name = 'wins'
-- deaths which aren't useful here so i got rid of them
    wins.Value = ds1:GetAsync(plr.UserId)
    ds1:SetAsync(plr.UserId, wins.Value)

    wins.Changed:connect(function(plr)
        ds1:SetAsync(plr.UserId, wins.Value)
    end)
end)
