How can I choose two random players that are not the same?

I'm trying to make a game that will teleport two players into an arena to fight. I've already made the script although whenever I run it sometimes it would only teleport one player. I want to grab two players that are not the same. This is my attempt

local NumbPlayers = #game.Players:GetPlayers()
	if NumbPlayers >= 2 then
                local randomPlayer1 = game.Players:GetPlayers() 
        [math.random(1,#game.Players:GetPlayers())]
                local randomPlayer2 = game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())]
                print(randomPlayer1)
                print(randomPlayer2)
                if randomPlayer2 == randomPlayer1 then
	          randomPlayer2 = game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())]
               end
end

I do have a bit of a precaution that if randomplayer2 is equal to randomplayer1 then it will choose a new player. Although sometimes that doesn't even work. Any help would be apreciated

So first, let's get the name of every player in a table:

local Players = {}

for _,v in pairs(game.Players:GetChildren()) do
	table.insert(holdPlayers, v.Name)
end

Now, let's choose the 1st player:

local Players = {}

for _,v in pairs(game.Players:GetPlayers()) do
	table.insert(holdPlayers, v.Name)
end

local 1stRandomNumber = math.random(1,#game.Players:GetChildren())
local 1stRandomPlayerName = Players[randomNum]
local 1stPlayer = game.Players:WaitForChild(1stRandomPlayerName)

Okay. Now, let's get the 2nd player:

local Players = {}

for _,v in pairs(game.Players:GetPlayers()) do
	table.insert(holdPlayers, v.Name)
end

local 1stRandomNumber = math.random(1,#game.Players:GetChildren())
local 1stRandomPlayerName = Players[randomNum]
local 1stPlayer = game.Players:WaitForChild(1stRandomPlayerName)

local 2ndRandomNumber = math.random(1,#game.Players:GetChildren())
local 2ndRandomPlayerName = Players[randomNum]
local 2ndPlayer = game.Players:WaitForChild(2stRandomPlayerName)

But we don't want that the 1st player the is the same as the 2nd player, so let's do a "repeat" function that randomizes again the 2nd player until we get another player that is not the 1st player:

local Players = {}
for _,v in pairs(game.Players:GetPlayers()) do
	table.insert(Players, v.Name)
end

local 1stRandomNumber = math.random(1,#game.Players:GetChildren())
local 1stRandomPlayerName = Players[randomNum]
local 1stPlayer = game.Players:WaitForChild(1stRandomPlayerName)

local 2ndPlayerIsNot1stPlayer = false -- variable for the repeating

repeat
	local 2ndRandomNumber = math.random(1,#game.Players:GetChildren())
	local 2ndRandomPlayerName = Players[randomNum]

	if 2ndRandomPlayerName = 1stRandomPlayerName then -- checking their names
		2ndPlayerIsNot1stPlayer = false
  	else
		local 2ndPlayer = game.Players:WaitForChild(2stRandomPlayerName) -- getting the 2ndplayer after making sure it's not the 1st player
		2ndPlayerIsNot1stPlayer = true
	end
until 2ndPlayerIsNot1stPlayer == true
-- Add what you wanna do here

It's a little bit long, but I hope it helped!

I haven't tested it, but this is probably the method I would go with. It's easy to understand and should work.

local Players = game.Players:GetPlayers()

local function ChooseRandom()
	local newRandom = math.random(1, #Players) --//Gets a random index inside of the Players table
	local newPlayer = Players[newRandom] --//Gets the player object from the Players table
	
	table.remove(Players, newRandom) --//Removes the player object that we just chose from the table
	
	return newPlayer --//Return our new random player
end

local FirstPlayer = ChooseRandom()
local SecondPlayer = ChooseRandom()
