Back in the day when this was possible (iBooks, Powerbooks, early-model MacBooks), I'd say that a large percentage of Mac laptops eventually did get upgraded. I certainly upgraded 100% of the Macs I owned and also did many for friends and family. Some models made upgrades quite easy: the RAM slots, especially, were often accessible without special tools. It was common to buy the base model Mac with the fastest CPU, then install your own RAM modules and big HDD/SSD to save money. Swapping HDDs out for SSDs was also, of course, a huge performance upgrade for a while.

Even non-technical users who wouldn't upgrade their Macs on their own would often trade them in to dealers/resellers who would refurbish and upgrade them for resale.
