When using a while loop, it doesn't use any of the wait variables i've used for delay. It just skips it all.

private int countdowntime = 4;
    private int countdowndelay = 0;
    private int countdownreach = 250;
    private boolean wait = false;
    
    public void countdown()
    {
        while (countdowntime > 0)
        {
            wait = true;
            countdowndelay++;
            if (countdowndelay >= countdownreach)
            {
                countdowntime--;
                Greenfoot.playSound("Countdown.mp3");
                countdowndelay = 0;
                String text = "";
                text = Integer.toString(countdowntime);
                this.showText(text,this.getHeight()/2,this.getWidth()/2);
                if (countdowntime == 1)
                {
                    countdownreach = Greenfoot.getRandomNumber(250);
                    countdownreach = countdownreach+250;
                }
                if (countdowntime == 0)
                {
                    countdownreach = 250;
                }
            }
        }
        countdowntime = 4;
        started = true;
    }
Why does it skip it all?

For context if my wording was wrong, where it has all the delays, I'm assuming it skips it straight too the countdownreach and it reaches the goal instantly, so instead of having a like 1-3 second delay, it skips to 0.

Nothing is skipped. A while loop (like a for or do loop) will execute until its completion within the act step. You are causing everything to be done at once by using the loop.

How would I be able to loop it until it gets to 0 without it going all at once? I want it to have a timer so it goes 3, 2, 1.

You can add: 
Greenfoot.delay(1);
to literally pause for a time frame. A simplified version would be like: 
int cdTimer = 181;

public void countdown()
{
    while (cdTimer > 0)
    {
        if ((--cdTimer)%60 == 0)
        {
            Greenfoot.playSound("Countdown.mp3");
            shotText(""+(cdTimer/60+1), getWidth()/2, getHeight()/2);
            Greenfoot.delay(1);
        }
    }
    started = true;
}
Or, even better: 
public void countdown()
{
    for (int i=3: i>0; i--)
    {
        Greenfoot.playSound("Countdown.mp3");
        showText(""+i, getWidth()/2, getHeight()/2);
        Greenfoot.delay(60);
    }
    started = true;
}
