i have one big while loop which loops all of my code and i have a small section within my code which is also in a while loop but i want to know is there a way to stop the middle while loop and go back to the main while loop

    while stats
            s=input ('would you like to see the game stastics 1,yes 2,no:');
            
            switch s
                
                case 1
                    num_player = 20;
            WLT = zeros(num_player,3);
            %disp stastics
            if have_a_winner
                WLT(winner_index,1) = WLT(winner_index,1) + 1;
                WLT(loser_index,2)  = WLT(loser_index,2) + 1;
            else
                WLT(player1_index,3) = WLT(player1_index,3) + 1;
                WLT(player2_index,3) = WLT(player2_index,3) + 1;
            end
                case 2
                        disp('main menu')
                        
                        playOn = false;
                        
                 
                    
                
            end
           continue
    end
    

this is my middle while loop which i want to cancel if case 2 is choosen and go back to the start of the program

while true % main while loop
    
    % some stuff happens
    
    stats = true;
    playOn = true;
    
    while stats % little while loop
        
        s=input ('would you like to see the game stastics 1,yes 2,no:');
        
        switch s
            
            case 1
                
                num_player = 20;
                WLT = zeros(num_player,3);
                
                %disp stastics
                if have_a_winner
                    WLT(winner_index,1) = WLT(winner_index,1) + 1;
                    WLT(loser_index,2)  = WLT(loser_index,2) + 1;
                else
                    WLT(player1_index,3) = WLT(player1_index,3) + 1;
                    WLT(player2_index,3) = WLT(player2_index,3) + 1;
                end
                
            case 2
                
                disp('main menu')
                playOn = false;
                break % exit the little while loop
                
        end
        
    end
    
    if ~playOn % start at the top of the main while loop again
        continue
    end
    
    % other stuff happens
    
end
