yes and no. people have different genetics that can make them sorta predisposed to developing certain habits like drug or alcohol addiction, hoarding, nail-biting, etc. but habits can also be learned. my sister has a habit of talking while facing away from you which she learned from our dad. if you’re really interested in this then i’d suggest looking into epigenetics. it’s how your environment and behaviours can change the way your body reads and understands DNA sequences. it’s pretty cool and may have some more in-depth answers to your question.
