erhm yes... thats exactly what the quote says...
soooooo i dont get you, you say this is no true rng but than you say there is no true rng ... what???
anyways, lets imagine they use the hashcode of the playername as seed (just imagine, i am not saying its a good thing ) xor with another more random number like the current ticks).
then obviously some players might be favored due to their name, but it still is true rng (http://en.wikipedia.org/wiki/Random_number_generation)
anyways lets get back to topic
