Why are the vains in my left arm/hand smaller than the vains in my right arm/hand? I'm wondering if my circulation is as good for both limbs

In brief: OK

It is rare that they are exactly the same since you do not use your hands equally.
The veins bring the blood back the heart. Your "circulation" to the hands is via your arteries.
