The probability of the problem occurring is vanishingly small - much smaller than a bit flip due to a cosmic ray in the machine computing it, leading to a wrong answer or a crash. And even that doesn’t matter, because the computations are repeated so often. Again, the application determines what the most suitable PRNG is.
