Aren't most PRNs made deterministically? LCGs can have huge cycle times and can produce statistically sound random numbers.

I had to look it up and Wikipedia has this statement a bit differently. This one makes Neumann sound funny because his Mid-Square method is a terrible PRN generator.

Pi itself is not a random number, for example, but the digits of pi are believed to be random in this way (what mathematicians describe as “normal”): Every integer from 0 to 9 appears about the same number of times.

Does this not make the digits of Pi discreetly distributed (an equal chance for each integer?)? Is the meaning of 'normal' here not referencing a normal distribution?
