Why wont this kill ALL the players?

this is my first attempt at for i,v in pairs() do so i got no idea what im doing wrong and i get no errors from this this is my local script

    local player = game.Players.LocalPlayer
    
        player.Chatted:Connect(function(msg)

if msg:lower() == "kill all" then

for i,v in pairs(game:GetService("Players"):GetChildren()) do

if v.ClassName == "Player" then

local players = v

game:GetService("ReplicatedStorage"):WaitForChild("killall"):FireServer(players)

end

end

end

end)

btw i have the msg function already and this is my server script

game.ReplicatedStorage:WaitForChild("killall").OnServerEvent:Connect(function(players)

players.Character.Humanoid.Health = 0

end)

The OnServerEvent's first parameter is the PlayerObject who fired the remote.

--Local Script
local arg1 = game.Players.Player
local arg2 = 'hi'
RemoteEvent:FireServer(arg1, arg2)

--Server Script
RemoteEvent.OnServerEvent:Connect(function(player, arg1, arg2)
    local player_who_FireServer = player
    local player_I_want_to_kill = arg1
    print(arg2)
end)

Output: hi

Note: I named the variables similar for explanation purpose.
