how to I make a gui that pops up for everyone at the same time and says the same thing?

I get so close but then I mess up. This is the hardest part of anything I have ever done. What I am trying to do is to make a GUI that pops up for everyone at the same time and says the same thing. I also am trying to make it so that it can be fired again so the rounds can keep on going. I have tried many things but they just don't work. If anyone has any tips or anything DM me. I really need help. I am at the point where I will PAY.

I had something like this before but I have no idea how re- fire it.

function update(count)
    local player = game.Players.LocalPlayer
    game.Players.LocalPlayer.PlayerGui.pods.ann.TextButton.Text = "Waiting for "..count.." more players!"
    if count <= 0  and game.Workspace.game.CanCollide == true then
        game.Players.LocalPlayer.PlayerGui.pods.ann.Visible = true
        game.Players.LocalPlayer.PlayerGui.pods.ann.TextButton.Text = "Welcome to the annual HUNGER GAMES"
        wait(10)
        game.Players.LocalPlayer.PlayerGui.pods.ann.TextButton.Text = "If you don't know how to play, read the description!"
        wait(10)
        player.TeamColor = BrickColor.new("Forest green")
        game.Players.LocalPlayer.PlayerGui.pods.ann.TextButton.Text = "Selecting random arena..."
        wait(5)
        game.Players.LocalPlayer.PlayerGui.pods.ann.TextButton.Text = "Arena selected. Prepare to enter the game. May the odds be ever in your favor."
        wait(20)
        game.Players.LocalPlayer.PlayerGui.pods.ann.Visible = false
                        game.ReplicatedStorage.Remotes.tp:FireServer()
end
while true do
    if game.Workspace.inter.CanCollide == false
        and game.Workspace.game.CanCollide == true
        then
        update()
        wait(1) 
game.Workspace.game.CanCollide = false
                    end
end
end
wait(5)
game.ReplicatedStorage.Notify.OnClientEvent:connect(update)

I tried to do remotes but it didn't work at all. here was the remote script

player = game.Players:GetPlayers()
while true do
    if game.Workspace.game.CanCollide == true
        and game.Workspace.PlayerCount.Players.Value < 5
        then
        game.ReplicatedStorage.Remotes.one:FireServer()
        wait(10)
        game.ReplicatedStorage.Remotes.two:FireServer()
        wait(10)
        game.ReplicatedStorage.Remotes.three:FireServer()
        wait(10)
        game.ReplicatedStorage.Remotes.four:FireServer()
        wait(10)
    end
end

and here was the first script a part of that

local player = game.Players:GetPlayers()
game.ReplicatedStorage.Remotes.one.OnServerEvent:Connect(function(qnay)
    player.PlayerGui.pods.ann.Visible = true
    player.PlayerGui.pods.ann.TextLabel.Text = ("Welcome to the annual HUNGER GAMES!")
end)
