Players cant see other people scores on the leaderboard (+not saving)?

I've been making a game where you have to click a button to gain jump power, but later I realized that the stats won't save and people can't see others score on the board, they only see their score. This is my local script for the button and my leaderboard. Tell me if you need to see other scripts or anything.

local script:

local player = game.Players.LocalPlayer
local jumpPower = player:WaitForChild("leaderstats"):WaitForChild("Jump Power")
local RS = game.ReplicatedStorage
local ClickedEvent = RS.Clicked

local debounce = false

function onClicked()
    if debounce == false then
        debounce = true
        jumpPower.Value = jumpPower.Value + 0.1
        if player:WaitForChild("PremiumDouble").Value == true then
            jumpPower.Value = jumpPower.Value + 0.1
        end
        ClickedEvent:FireServer()
        script.Parent.Sound:Play()
        wait(0.2)
        debounce = false
    end
end

script.Parent.MouseButton1Click:Connect(onClicked)

leaderboard:

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("SkinStats") -- maybe this needs to be changed lmk

game.Players.PlayerAdded:Connect(function(Player)
    local Leaderstats = Instance.new("Folder")
    Leaderstats.Name = "leaderstats"
    Leaderstats.Parent = Player

    local JumpPower = Instance.new("NumberValue")
    JumpPower.Name = "Jump Power"
    JumpPower.Value = 0
    JumpPower.Parent = Leaderstats

    local Wins = Instance.new("IntValue")
    Wins.Name = "Wins ????"
    Wins.Value = 0
    Wins.Parent = Leaderstats

    local PremiumDouble = Instance.new("BoolValue")
    PremiumDouble.Name = "PremiumDouble"
    PremiumDouble.Parent = Player

    local Data = DataStore:GetAsync(Player.UserId)
    if Data then
        JumpPower.Value = Data
        Wins.Value = Data
    end
end)

game.Players.PlayerRemoving:Connect(function(Player)
    DataStore:SetAsync(Player.UserId, {
        ["Cash"] = Player.leaderstats["Jump Power"].Value; 
        ["Kills"] = Player.leaderstats["Wins ????"].Value; 
    })
end)
