Validity of stories

Hello Rabbi,
From what I understand, the rabbi claims that there is nothing to learn from the stories in the Bible because they do not lead to any practical validity. That is, even if a person learns from the story something that does not fit his values, he will not change himself according to what he learned (contrary to the halakha, which states that a person must arrive at a certain practical thing that can oppose his values). From this, the rabbi concludes that there is no value in the stories in the Bible, or at least no value that we can learn.
But why not say that although stories do not change a person’s perception in a practical way, they do change a person’s thoughts. One could say that stories can influence a person. Not on such a high level as halakha, but yes on a certain level.
From this we can say that there is also a certain interest in studying the Torah itself and not every story. Every story has its own effects on a person, and not everything can be learned from every story. We can assume that God gave us certain stories that will influence the thoughts of people so that they will lead us to a better place.
What does the rabbi think?
