Why is there no leader board appearing in studio and in server?[EDIT]

So, I'm currently learning about Leader boards. I've read so far the whole wiki page, but now that I did what their script says, nothing appears. Here's the script:

game.Players.PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("Model")
	leaderstats.Name = "Points"
	leaderstats.Parent = player
	
	local coin = Instance.new("IntValue")
	coin.Value = 0
	coin.Name = "Coins Collected"
	coin.Parent = leaderstats
end)

Any ideas as to why nothing is appearing? All help is appreciated!

[EDIT PART]

So I've noticed that ROBLOX's script work's fine:

game.Players.PlayerAdded:connect(function(player)
     local leaderstats = Instance.new("Model")
     leaderstats.Name = "leaderstats"
     leaderstats.Parent = player
 
     local money = Instance.new("IntValue")
     money.Name = "Money" 
     money.Value = 0 
     money.Parent = leaderstats
 end)

What's the difference between my script, and theirs?
