I researched a bit and it seems chip shortage was building before the pandemic, but got really bad when it started. Numbers of shipped GPUs between extremely good year of 2017 and 2021 are drastic. Here are some sources, though I cannot say if they are completely correct:
"Nvidia and AMD shipped 12.7 million cards in 2021, which is an increase of over 1 million compared to 2020."
This would mean 24,4 million units in 2020 and 2021 combined.
Despite the persisting chip shortage and extremely high GPU prices, graphics card shipments increased by 25% compared to 2020.

Behind the link there is a table stating dGPU shipments were overall 92,8 million units in 2017.
This statistic shows the quarterly shipments of discrete graphics processing units (GPUs) worldwide from 2015 to 2018.

From these numbers I would conclude the demand is way over supply, which the pandemic has only increased due to people spending time at home. Consoles were hard to get for more reasons than only the GPU chip, they include various chips. GPU chips inside consoles are not sold to miners, naturally.
I would state, by now, when already over a quarter of the 2017 numbers are shipped counting from the beginning of 2020, many gamers would have their new GPU, but in reality not many gamers have upgraded their GPU in recent times. Even though the shipment numbers are historically low, the situation points to miners being a big problem.
