"Is it that chance and randomness are fundamental aspects of our world, or is it that our knowledge of the world is inherently limited [..]"

Both. The latter is obviously true, and quantum physics tell us that the former is also true.

And the author knows (this in the book):

"Elements of quantum mechanics are also involved, and this allows the author to demonstrate how probabilistic laws are basic to microscopic phenomena."

True is a dangerous word to use in science, since our understanding can always change. What QM tells us is that our best understanding of the world at the micro physical is based on probability. Whether this is actually true of the world is open to interpretation.
