No. The majority of the additional memory capacity comes from trickery like "allocate on write" and "copy on write". For example, maybe you have a 2 MiB executable file with one copy of the file's data in a file system cache, plus 4 more copies of the same file's data being used by 4 processes; and this will not cost you 10 MiB of RAM, and will probably cost you a little more than 2 MiB of memory because only things that were actually modified need to be different. Further, maybe each of those 4 processes have 1 GiB of virtual memory for ".bss" and heap; but it's mostly all full of zeros so it doesn't actually cost you 4 GiB of RAM and you only pay for the pieces that were actually modified.

This is where segmentation is a crippled joke - if you modify a handful of bytes in a segment then you end up needing to allocate actual RAM to cover most of (the entire?) segment (and not just the handful of pages that were modified), so all the RAM you could've avoided using gets wasted.
