I thought that pseudo random referred to the way that the seed number was generated. Like, by sampling disk I/O metrics, thermometer readings, and mouse movements and combining them together. Pretty random, but still predictable in certain ways. If you wanted a truly random seed, you'd need to sample something the physicists say is actually random, such as cosmic microwave background radiation or certain subatomic processes following the uncertainty principle.

Did I learn wrong? Are all random numbers derived from an appropriate recursive function considered pseudo random, no matter how the seed was derived?
