I purchased (2) 12-tb: anyone knows why i get 10.91-tb for each? why are we short?

Hard drive manufacturers use base 10 for size. So 1 TB = 10**12 bytes. Your system uses base 2 for counting, so 1 TiB = 2**40 bytes. A base 2 TiB is larger than a base 10 TB. The actual name for a base 2 terabyte is a tebibyte, or TiB. A base 10 TB is TB or terabyte.

Can this be used as a normal hdd storage drive for a desktop pc?

Quick answer YES The more complete answer starts with 'WHY'? First, NAS rated disks are typically more expensive than desktop drives. They are built for different use expectations. One of the answers mentioned always leaving the system powered on. Most NAS setups are powered on and left on. They do not power cycle (and more importantly heat cycle) with any regularity. As such, the drives are built to operate in that environment. Another answer mentioned RPMs and many NAS drives spin at 5400/5900 RPMs. This means that the place on the platter where you file is stored takes longer to rotate around than it would on a typical desktop drive of 7200 RPM. Another answer mentioned vibration. The desktop is less vibration isolated (typically) than a NAS setup. Shop a 7200 (or faster) RPM disk or consider NVMe or SSD is the budget allows. You will not only likely save money initially but will have better performance in the longer term.

Is this drive smr if so i don't want it!

At least the IronWolf Pro drives are all CMR (=PMR), and not SMR. I think some of the smaller capacity non-Pro drives used to be SMR, but I think now even they are all CMR.

Does this drive come with sata cable?

No it's a bare drive no screws no cables.
