You’ll need to use a DataStore, although you likely already know this.

DataStore is required for these kinds of things, you can learn Datastore by watching Videos of Tutorials from Youtube

local datastores = game:GetService("DataStoreService")
local datastore = datastores:GetDataStore("DataStore")
local players = game:GetService("Players")

local function deserializeData(player, data)
	local leaderstats = player.leaderstats
	for statName, statValue in next, data do
		local stat = leaderstats:FindFirstChild(statName)
		if statName then
			stat.Value = statValue
		end
	end
end

local function serializeData(player)
	local data = {}
	local leaderstats = player.leaderstats
	for _, stat in ipairs(leaderstats:GetChildren()) do
		data[stat.Name] = stat.Value
	end
	return data
end

local function onPlayerAdded(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local knockouts = Instance.new("IntValue")
	knockouts.Name = "Knockouts"
	knockouts.Parent = leaderstats
	
	local wipeouts = Instance.new("IntValue")
	wipeouts.Name = "Wipeouts"
	wipeouts.Parent = leaderstats
	
	local success, result = pcall(function()
		return datastore:GetAsync("Stats_"..player.UserId)
	end)
	
	if success then
		if result then
			deserializeData(player, result)
		end
	else
		warn(result)
	end
end

local function onPlayerRemoving(player)
	local data = serializeData(player)
	
	local success, result = pcall(function()
		return datastore:SetAsync("Stats_"..player.UserId, data)
	end)
	
	if success then
		if result then
			print(result)
		end
	else
		warn(result)
	end
end

local function onServerShutdown()
	for _, player in ipairs(players:GetPlayers()) do
		local data = serializeData(player)

		local success, result = pcall(function()
			return datastore:SetAsync("Stats_"..player.UserId, data)
		end)

		if success then
			if result then
				print(result)
			end
		else
			warn(result)
		end
	end
end

players.PlayerAdded:Connect(onPlayerAdded)
players.PlayerRemoving:Connect(onPlayerRemoving)
game:BindToClose(onServerShutdown)

Here you go, I just wrote this multi-purpose script which is able to store all leaderstats (regardless of the types of values/names of values used).
