How to save 2 Data Stores via Tables?

When he leaves you are obviously going to want to save the data. The best way to do this is in a PlayerRemoving function. A function that runs when the player leaves the game.

game.Players.PlayerRemoving:Connect(function(Player)




end)

The next thing your going to want to do is reference the data. I personally do not know how your data is stored so the next part will likely need to be edited depending on your situation.

game.Players.PlayerRemoving:Connect(function(Player)

--This is based off the assumption your data is stored like this. Obviously your data might be saved differently so you'll want to correctly reference it in the table. (I can't just type Points.Value because its a separate function obviously.)

local Data = {

        Points = Player.leaderstats.Points.Value
        Wins = Player.leaderstats.Wins.Value
}


end)

The final part you are going to want to do is save this to the player. To do this you are going to need a key. Something which you can identify for each individual player. You are then going to need to try and save that (doing it in a pcall in case it fails).

The final result should look something like this:

--This Gets The Data Store:

local DataStoreService = game:GetService("DataStoreService")

--This Creates The Game Data Store With The Name Of Game Data:

local GameDataStore = DataStoreService:GetDataStore("GameDataStore")

game.Players.PlayerRemoving:Connect(function(Player)

--This is based off the assumption your data is stored like this. Obviously your data might be saved differently so you'll want to correctly reference it in the table. (I can't just type Points.Value because its a separate function obviously.)

local Data = {

        Points = Player.leaderstats.Points.Value
        Wins = Player.leaderstats.Wins.Value
}

--This is the key:
local PlayerUserId = "Player_"..Player.UserId

--Wrapped in a pcall this saves the data to the data store
    local Success, ErrorMessage = pcall(function()
        GameDataStore:SetAsync(PlayerUserId, Data)
    end)


    --We know the datas saved:
    if Success then
        print("Data Saved.")
    else
    --Data didn't save:
        print(ErrorMessage)
    end 
end)

When loading the data you are obviously going to need to reference the key. However since this question was purely about saving data on removal I will only be answering that. (+ if I did much more I would practically be scripting your data save system)
