One important point that the video has missed (since it appear to be very analytic and professional) is our taste change as we drink more. Typically beginners just look for fruity, easy to drink simple wine because they consider wine as just grape juice + alcohol.
As they drink more, they prefer more complexity, look for more details like balance, finish etc
For the experienced drinkers, they may even require "expression" of certain characteristics.
Just like when 鬼老 first eat Chinese food, they prefer 香口 dishes like sweet and soar ribs, bbq pork etc. and don't know how to enjoy steam fish until they have ate a lot of Chinese food.
