Prophecies are self-fulfilling. If they are unheard, unspoken, do they still come to pass? If you think I have ever told someone every single prophecy I've ever had, you're mistaken. My secrets are as numerous as they are dangerous.
And divination isn't just predicting the future. There are branches, like scrying which allows you to look into places or upon people from the safety of your own room. Or you can ask questions through cards, casting the bones, so on. That is what I was doing.
