I mostly use the numbers on the labels for comparison purposes between different items, rather than trying to make sure what I eat adds up to 100% of everything. (I take vitamins anyway, to be on the safe side.) But you're right, the %s listed are generalizations, and not to be taken as specific to individuals.
That is another difference in current labels versus the ones I remember from the past: The old ones used to mention RDA, or Percent of Recommended Daily Allowance, while the new ones mention DV or % Daily Value. I'd thought it was simply a new term for the same thing... which based on the following I think it is, but it's also more complicated than that: https://blog.watson-inc.com/marketing/rda-vs.-rdi-vs.-dv-how-are-they-different
I did a search to find examples of food labels from the 1970s and 1980s to compare against my memories, but not many of the results indicate a specific time period and also have legible images of the nutrition facts section.
