only i (the owner) can see the leaderboard in real game and studio?

i have a leaderboard script set up in workspace and this is it..

--Variables
local leveldata = game:GetService("DataStoreService"):GetDataStore("level")
local EXPdata = game:GetService("DataStoreService"):GetDataStore("EXP")
local xpLeveldata = game:GetService("DataStoreService"):GetDataStore("xpLevel")
local Golddata = game:GetService("DataStoreService"):GetDataStore("Gold")
local HttpService = game:GetService("HttpService")


--Data Storage Save
function savedata(dataname, playerid, value)
    game:GetService("DataStoreService"):GetDataStore(dataname):SetAsync(playerid, value)
end

--Leaderboard Variables
game.Players.PlayerAdded:connect(function(player)
    playerKey = "user_"..player.userId  -- user key

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    --Gold
    local gold = Instance.new("IntValue")
    gold.Name = "Gold"
    gold.Value = Golddata:GetAsync(playerKey) or 0
    gold.Parent = leaderstats


    --Level
    local level = Instance.new("IntValue")
    level.Value = leveldata:GetAsync(playerKey) or 1
    level.Name = "Level"
    level.Parent = leaderstats


    --XP
    local EXP = Instance.new("IntValue")
    EXP.Value = EXPdata:GetAsync(playerKey) or 0
    EXP.Parent = player
    EXP.Name = "Exp"

    --XP Needed
    local xpLevel = Instance.new("IntValue")
    xpLevel.Value = xpLeveldata:GetAsync(playerKey) or 500
    xpLevel.Name = 'ExpNeeded'
    xpLevel.Parent = player



game.Players.PlayerRemoving:Connect(function(player) -- save player stats
    savedata('level',playerKey,player.leaderstats.Level.Value)
    savedata('EXP',playerKey,player.Exp.Value)
    savedata('xpLevel',playerKey,player.ExpNeeded.Value)
    savedata('Gold',playerKey,player.leaderstats.Gold.Value)
end)

sorry, very hefty amount of code but my datastore is combined in there. i just want to know why i am the only one who can see the leaderboard.
