Can life really be worked out?

I think fortune telling is unscientific, but people often say, believe it or not. Just like there is no ghost, maybe the fortune teller is talking nonsense, and you happen to be guessed by him, so you think your life can be calculated in advance. Then everyone went to tell a fortune. Isn't the world chaotic? I believe that life is in our own hands, and good people are safe all their lives.
