Missing date in 'About this mac' window

I'm looking for used macbook pro and found this one. Why there is no date of manufacture in 'About this mac' window? Can it be hacked mac? Also on second screen shot there is mystical '1Tb flash storage', does it mean 1Tb SSD or why then this hard drive called 'flash storage'?

There are other places in About this Mac, that can give you a hint, like Install date for applications.

Flash storage means SSD. Apple started selling MBP with 1Tb SSD from 2013. You can check your specific model using the serial number at Apple.

I did the check on Apple web site and it say you have a MacBook Pro (Retina, 13-inch, Late 2013)

Here is the full report:

If you are trying to figure out which model of Macbook Pro that is, you can use the serial number from the screenshot.

Just enter the serial number on a site like EveryMac's Ultimate Mac Lookup and it will tell you about the Mac. For example the below link tells you that this is a Late 2013 Macbook Pro.
