Why doesn't IF suddenly work?

Question

Java

Hello, I'm trying to solve the task "snail race" in which as soon as any of the "snails" scores 50 points, the game stops.
I don’t understand why it doesn’t work and the cycle ends somewhere around 18 or 20? Whereas if you replace with - the principle works but a little crooked - the array is checked to ensure that all its elements have reached a state less than 50 - so while is not suitable. I don't understand what's wrong? After all, when used for each element of the array, the program should be launched every time the element < 50 and for some reason it stops .. Thank you!if (tab[z] < 50)

while (tab[z] < 50)

if

public static void main(String[] args) {
        int dice;
        int[] tab = new int[3];


        System.out.println("\n\t -= SNAIL RUN =- ");

        for (int z=0; z<tab.length;z++){
            if (tab[z] < 50)  {

                System.out.println("\n");
                for (int i=0; i<tab.length; i++) {

                    // Generating random numbers
                    dice = ThreadLocalRandom.current().nextInt(1, 6 + 1);
                    tab[i] += dice;

                    System.out.print("Dice"+(i+1)+"="+dice+" | ");
                }

                System.out.println("\n");
                for (int i=0; i<tab.length; i++){
                    System.out.print(tab[i] + " | ");
                }

                System.out.println("\n________________________________________________________________");

            }
        }

        System.out.println("\nGAME OVER");

Because all the application logic is run for each element from the tab.
It should be something like this:

int dice;
        int[] tab = new int[3];
        boolean gameOver = false;


        System.out.println("\n\t -= SNAIL RUN =- ");

        while (!gameOver) {
            System.out.println("\n");
            for (int i = 0; i < tab.length; i++) {

                // Generating random numbers
                dice = ThreadLocalRandom.current().nextInt(1, 6 + 1);
                tab[i] += dice;

                if (tab[i] > 50) {
                    gameOver = true;
                }

                System.out.print("Dice" + (i + 1) + "=" + dice + " | ");
            }

            System.out.println("\n");
            for (int i = 0; i < tab.length; i++) {
                System.out.print(tab[i] + " | ");
            }

            System.out.println("\n________________________________________________________________");
        }

        System.out.println("\nGAME OVER");
