I’d second Bob’s comments. Growing potatoes from other potatoes (or parts thereof), the new plant is a clone of the original. Just as your seed potatoes would be.
The risks in using grocery store potatoes is possible disease contamination (although you should be able to see scab and reject or cut that part out), and some risk that those potatoes were chemically or heat treated to kill the eyes. But if you buy potatoes that are starting to sprout, no worries on that score
