Linux – Different physical usage of cPanel storage with the free -m command and top terminal

So I have a cPanel access. In cPanel statistics, I can see that my physical memory usage is 2GB and almost full.

Use of physical memory in cPanel

When I go to the terminal and run free -m I got that:

                                                    total used free shared buffer cached
Mem: 257680 232988 24692 10514 26825 152897
- / + buffer / cache: 53265 204415
Swap: 7811 0 7811

As we can see, the total physical memory is about 257 GB. Then I assume that it is the memory of the real computer (not just for my hosting server).

Then I tried to run above Command:

top - 16:37:43 from 118 days, 9:51, 3 users, load average: 16.32, 15.80, 18.41
Tasks: 4 total, 1 running, 3 sleeping, 0 stopped, 0 zombie

And I understood that. As we can see, the total memory is still at 263 GB.

But when I summarize the virtual VIRTIt is only about 600 MB in size. The value here does not represent the value in free -m, Header on aboveand even cPanel statistics.

What is missing here?

Add to that the result, when I run cat / proc / meminfo:
