Why some divination is really accurate.

Once a fortune teller went to our place, and my mother and two other people (one called grandma and the other called aunt) went to see the fortune teller. It is said that there is no charge for the first divination. If it is accurate, it will be collected from the second divination. The grandmother who counted first said that grandma lost a grandson, but another grandson will be born, which is a blessing. The result is really like this. My grandmother's daughter-in-law miscarried and gave birth to a son the next year. And then count my mother. My mother asked him to calculate how many children he had, whether it was a boy or a girl. Mr. Wang said that my mother has two girls (this is the reality). My mother told him it was wrong. There is a man and a woman. Mr. Wang still insists that my mother has two daughters. He also said to my mother: say you are blessed, say you are not blessed, and not blessed. I'm really ashamed to hear that. If it is not a great blessing, I think all my efforts are boring. Be a kind heart. There is also an aunt, and the calculation is quite accurate. At this moment, a familiar grandmother passed by and my mother called her. But she just didn't count, and the fortune teller didn't take the initiative to count for her, just gave her a look. Soon after, she got lung cancer and died soon after.

Is the fortune teller really accurate? Should I believe it or not? I don't care about others, saying that my mother said that she is blessed and blessed, and she is not blessed. This worries me! If you don't believe me, how can a fortune teller work out the accurate things ahead?
