The fortune teller said that I was unlucky and tried not to go out. Is the blind man's fortune telling accurate?

To tell the truth, this is unscientific for the current scientific development! For example, if everything goes wrong today, you will naturally think of what a fortune teller said a few days ago. Everything has been going wrong recently. In this way, you will believe something. In fact, this is the so-called cause and effect. Because, the blind man said, if there is, then you will think of the cause! Anyway, it's just one sentence. Believe it or not, it is invalid.
