How to Use PlaceID to find Total Number of Players?

So, I don't really have much besides some code that I tried to find, but I'm trying to find the total number of players in the game using the PlaceID..

I don't know what to use, besides these codes.

local gameid = 970631874

local NumPlayers = #game.Players:GetPlayers();

For the #game, how would I correlate that to the gameID instead of the server game?

My explanation is really bad, but I have a lobby. And from there, I'm going to have 4 different teleporters that will teleport to different places. I was wondering if I could get the total amount of people playing that exact game.

-- inside the brick where it finds all the players

while true do
wait(0.2)
if game.Players.NumPlayers == 1 then --instead of the server that it is in, how to make it a specific PlaceID?
script.Parent.Text = "There is " ..game.Players.NumPlayers.. " player online"
else
script.Parent.Text = "There are " ..game.Players.NumPlayers.. " players online"
end
end

-- serverside

game.Player.PlayerAdded:connect(function()
game:GetService("DataStoreService"):GetDataStore("Plrs"):IncrementAsync("Players",1)
end)

game.Player.PlayerRemoving:connect(function()
game:GetService("DataStoreService"):GetDataStore("Plrs"):IncrementAsync("Players",-1)
end)

Hopefully these codes will help to make a solution.
