The article is correct. It’s the amount of ram the program asked for (virtual memory I think) The kernel has reserved address space but has not used ram until the program accesses it. There is a separate metric for ram actually in use by a program. But that number isn’t an ideal “ram used” because it doesn’t account for compression or swap. Linux is basically the same.
