How do I reset my Datastorage for everyone in this script?

for more context, the name of the Modul Script is PlayerManager

local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local PlayerData = DataStoreService:GetDataStore("PlayerData")

local function LeaderboardSetup(value)

    local money = Instance.new("IntValue")
    money.Name = "Money"
    money.Value = value
    money.Parent = leaderstats
    return leaderstats
end

    local success, result = pcall(function()
        return PlayerData:GetAsync(player.UserId)
    end)
    if not success then
        warn(result)
    end
    return success, result
end

local function SaveData(player, data) -- change data
    local success, result = pcall(function()
        PlayerData:SetAsync(player.UserId, data) -- change data
    end)
    if not success then
        warn(result)
