Look carefully at the red one!

Hi xor
That is the  virtual  size of the process.
It represents how much address space the process can access.
Not all of those addresses actually have anything mapped to them.

VIRT stands for the virtual size of a process, which is the sum of memory it is actually using, memory it has mapped into itself (for instance the video card's RAM for the X server), files on disk that have been mapped into it (most notably shared libraries), and memory shared with other processes. VIRT represents how much memory the program is able to access at the present moment.
