why doesnt this kick the player?

i want the player to get kicked if they dont have a certain gamepass or not have admin in their backpack this is a server script:

local firstpos
while wait() do
	for i,v in pairs(game.Workspace:GetChildren()) do
		if v:FindFirstChild("HumanoidRootPart") then
			if v.Humanoid.Sit == false then
			local person = v.HumanoidRootPart
			firstpos = person.Position
			wait(1)
			if (firstpos - person.Position).magnitude > 32 then
				print((firstpos - person.Position).magnitude)
				local player = game.Players:GetPlayerFromCharacter(person.Parent)
				if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId,6451920) or player.BackPackFindFirstChild("admin") then
			print("wont kick u bruh")
				else
					player:Kick("im better")
				end
			end
			if v.Humanoid.Sit == true then
				local person = v.HumanoidRootPart
			firstpos = person.Position
			wait(1)
			if (firstpos - person.Position).magnitude > 166 then
				print((firstpos - person.Position).magnitude)
			local player = game.Players:GetPlayerFromCharacter(person.Parent)
			player:Kick("silly u, im better")
			end
			end
			end
	end
end
