Earlier quoted context omitted.
If you look at sales chart, Sony is selling as many PS5 as they sold PS4 during the same launch period. It's just that demand is higher; the fact that they are able to make as much during a chip shortage says a lot of their supply chain expertise (same could be said of MS, Nintendo, Samsung, LG, Apple etc.).
Expertise being a euphemism for relationships to skip the queue.
How many people do you think they have dedicated only to supply chain management ? This is such a wide domain, we don't see it all from here: they have engineers dedicated to sourcing, to manufacturing, testing, evaluating new sources; people in charge of a given supplier; people in charge of the various type of transport, of recycling, etc. All this is in-house expertise, and definitely gives them an edge.
If you look at most big auto manufacturers; they too are suffering from shortages. So it seems tech giants must be doing something better.
