If you chose those digits from the same point every time, you'd get the same result every time. If you chose them starting from where you left off the previous time, everybody would still know what the winning numbers would be.
So, you need to have a random starting point in the decimal representation of pi, and you still need a source of random numbers. Since you need that source anyway, sending its output through pi seems a needless step.

But, you need to choose a starting point.
