So, my assumption is these files are created when i run lvcreate. Correct me if I'm wrong.
Yes, you are correct.

...if we can use this as instead of /dev/mapper/logvol's in the /etc/fstab?
If you do an "ls -l" on /dev/mapper/* it will tell you that those are symbolic links to the /dev/dm-* files. Files in /dev/mapper are named according to the volume groups and logical volumes lying on top of them. If you are comfortable with dm-* files and you know what volume group-logical volume they map to, you may use them in /etc/fstab file.
