Many fortune tellers say I can't get married until I'm thirty. Is it credible?

I'm not sure about it. My father is a small boss and used to be a carpenter when he was not in business. Once he was stabbed in the foot by a rusty nail at work, and then the rust poison entered his blood and almost destroyed his whole foot. He went to the hospital for a while. Later, my mother found a fortune teller and said that my father's feet would be fine in 2008, and our family will be rich from then on. He also said that one of the legs of my parents' bed was going to rot. There was a ball of cotton near the leg of the bed, and there was a nest of mice in the cotton.
