The C64 sold "between 12.5 and 17 million units" in its lifetime [0], vs. worldwide PC shipments of "71.5 million units in the fourth quarter of 2025." (emphasis mine) [1] It's truly an apples (hehe) to oranges comparison, and in my opinion it only reinforces the point that "normal people" will no longer be able to purchase computers, just like the C64 was not a mainstream product.
