Can a body get used to unnatural multivitamins and be inable to obtain the natural vitamins from food? How frequently does that happen?

In brief: It doesn't
Food, supplements and vitamins are broken down into their components in the normal process of digestion.
These small molecules are then absorbed and find their way to where they are needed in the body. The components of multivitamins, when broken down, are not unnatural and the body makes no distinction about the source.

In brief: No
I have never heard that your body can become unable to absorb vitamins from natural foods by taking multivitamins.
I don't believe that can happen. If you stop taking multivitamins, you may want to consider taking vitamin d (commonly low) if you are a man, plus vitamin B12 if vegetarian, iron if you are a menstruating woman, Folic Acid if planning pregnancy, and calcium plus d if postmenopausal.
