How would I make the loop stop if everybody dies in the map, or everyone wins?

Hello! I have a GameScript which runs all the time, and I am trying to make it so if all the players in the map die, or if the winners are greater than the number of players in my map, to stop running the loop, and go on to the next block of code. I have a folder that contains all the string values of the players names who are in the map there, and i have a folder that contains all the string values of the players that have won. How would I make this work?

for i = 200,0,-1 do
    status.Value = "In-game: "..i
    wait(1)
end
