I don’t mean Ambidextrous!
Yesterday I tried cutting a vegetable with the knife in my non-dominant hand and it was a weird and uncomfortable thing. I wonder if there are people who have that distinct discomfort of using your “bad” hand, but on both hands?
I don’t think it would fall under ambidexterity, because that kinda implies someone is comfortable with either hand, but could someone be uncomfortable with both?
Ambidexterity is the word you’re looking for. And yes it exists, but still people will often have a preference because they’re used to using a certain hand for certain tasks.

As for your question. Being uncomfortable with both hands is basically learning a new task. Like a baby learning to stack blocks.
