For 13 to be unlucky would require there to be some kind of cosmic intelligence that counts things that humans count and that also makes certain things happen on certain dates or in certain places according to whether the number 13 'is involved' or not (whatever 'is involved' might mean).
Interpretation
The quote questions the idea of luck and superstition associated with the number 13.
Douglas Hofstadter's quote reflects on the superstition surrounding the number 13, suggesting that for it to have any significance or to be deemed unlucky, there must be a cosmic intelligence that influences reality according to human perceptions of numbers. It challenges the validity of attributing luck to numerical associations and implies that such beliefs are arbitrary constructs of human thought.

A discussion about the impact of superstitions on life decisions.
You can imagine a soul as being a detailed, elaborate pattern that exists very clearly in one brain. When a person dies, the original is no longer around. But there are other versions of it in other people's brains. It's a less detailed copy, it's coarse-grained.
I would proclaim that the vast majority of what [say, Scientific American] is true-yet my ability to defend such a claim is weaker than I would like. And most likely the readers, authors, and editors of that magazine would be equally hard pressed to come up with cogent, non-technical arguments convincing a skeptic of this point, especially if pitted against a clever lawyer arguing the contrary. How come Truth is such a slippery beast?
What is an "I", and why are such things found (at least so far) only in association with, as poet Russell Edson once wonderfully phrased it, "teetering bulbs of dread and dream" - that is, only in association with certain kinds of gooey lumps encased in hard protective shells mounted atop mobile pedestals that roam the world on pairs of slightly fuzzy, jointed stilts?
Many people believe that our lives end not when we die but when the very last person who knew us dies. Memory is part of it, yes, but I think it's much more than memory.
Enormous numbers of people are taken in, or at least beguiled and fascinated, by what seems to me to be unbelievable hocum, and relatively few are concerned with or thrilled by the astounding-yet true-facts of science, as put forth in the pages of, say, Scientific American.
Sometimes it seems as though each new step towards AI, rather than producing something which everyone agrees is real intelligence, merely reveals what real intelligence is not.
The law of God cannot be fulfilled by external obedience.
Eventually everything connects - people, ideas, objects. The quality of the connections is the key to quality per se.

All our scientific and philosophic ideals are altars to unknown gods.
Capitalism has triumphed all over the world, but this triumph is only the prelude to the triumph of labour over capital.
It is the same India which has withstood the shocks of centuries, of hundreds of foreign invasions of hundreds of upheavals of manners and customs. It is the same land which stands firmer than any rock in the world, with its undying vigour, indestructible life. Its life is of the same nature as the soul, without beginning and without end, immortal; and we are the children of such a country.
