I don't believe in such things, It is a simple general prediction of daily normal life.
And for sure that 1 or more people on the 1 million+ people reading the horoscope will have the same "normal" faith just like the horoscope told them.
Now just like the "gossip theory" it would be like a domino effect if someone told someone that his/her horoscope prediction come true, people will start spreading it and even though not all people will believe it but surely some of them will and soon will spread the word if their horoscope prediction come true too.
