Why are fortune tellers sometimes accurate? Is there a scientific basis?

It is a fact that some people are accurate when they open their eyes. But people who open their eyes are not necessarily accurate, because some people see the truth and some people see the falsehood. In addition, almost all fortune tellers are liars. They calculate in a certain way and method, and even guess at random, which is completely wrong. Therefore, we should grasp the current things and don't listen to them easily.
