How is that predictions made by astrologers turns true?

Astrology can't be proved, but evidence can be shown. And by predictions, I don't mean predictions you read on daily or get it from net. I observe that real predictions made by genuine astrologers work out in lives of many, including me. If you visit Horoscope section, you will find a lot of questions from people, particularly Indians about marriage, career etc and we astrologers predict their future and suggest some remedies. Many who have experienced it, have replied us that it truly works.
