The digits of pi can pass some statistical tests of randomness but isn't in fact random, because it's the digits of pi - as you note there's an algorithm for producing it. As I mentioned, there are some problems with giving a rigorous definition of randomness, but one of the main approaches is through Kolmogorov complexity: "Kolmogorov's definition of a random string was that it is random if it has no description shorter than itself via a universal Turing machine." https://en.wikipedia.org/wiki/Random_sequence#Modern_approaches https://en.wikipedia.org/wiki/Random_sequence#Modern_approac...
