There's actually an easy explanation for our abundance of gold,
The article was on work detailing the abundance in the universe, as well as explanations for it - the work shows the explanations are complex.
Despite that complexity many element abundances are explained, some are not and some like gold are IIRC (I browsed the paper days ago) nearly so - the work in progress is promising.
"Something is raining gold across the universe." I don't know why they mentioned gold or in part of the article refer to recent work looking specifically on element isotope abundances in our own system to study local sources but at a guess it makes the article more click-worthy. I don't think there is an unusual amount of gold in our system or that it was discussed in the work, but maybe I have missed that - but as you say, some sources are local (and recent) so our mileage may vary on the average abundance. C.f. how our solar system was believed to be uncommonly metal rich, but with better statistics it lies just at the edge of the median peak so nothing but random outcome on most elements.
Uneven distribution of crust elements is curious though. Seems to me the claim among geologists is that generic sorting is thermal due to magma melts (I may have gotten that wrong, I read that in passing the other day and haven't checked it yet). But there are also biosphere mechanisms that for instance laid down banded iron formations and pyrite ("fool's gold").
By your prompting me to search, I see that gold is a bit complex in that regard. Gold belongs with rare earth elements to the element group that mostly sank to the core during Earth accretion, so the current abundance is due to later impacts.
And gold sorts in many ways: "On Earth, gold is found in ores in rock formed from the Precambrian time onward.[66] It most often occurs as a native metal, typically in a metal solid solution with silver (i.e. as a gold silver alloy). Such alloys usually have a silver content of 8–10%. Electrum is elemental gold with more than 20% silver. Electrum's color runs from golden-silvery to silvery, dependent upon the silver content. The more silver, the lower the specific gravity. Native gold occurs as very small to microscopic particles embedded in rock, often together with quartz or sulfide minerals such as "fool's gold", which is a pyrite.[67] These are called lode deposits. The metal in a native state is also found in the form of free flakes, grains or larger nuggets[66] that have been eroded from rocks and end up in alluvial deposits called placer deposits. Such free gold is always richer at the surface of gold-bearing veins[clarification needed] owing to the oxidation of accompanying minerals followed by weathering, and washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets."
