What can tarot cards tell you?

I'm curious, what exactly can tarot cards reveal to someone who seeks their guidance? Are they merely a tool for entertainment or do they hold deeper meaning? Can they offer insights into one's future, or are they merely a reflection of our own thoughts and feelings? I'm interested to know if they have any scientific basis or if they're purely based on intuition and the interpretation of symbols. Can tarot cards be used for personal growth, or are they limited to predicting outcomes? And finally, what are the risks involved in consulting tarot cards, if any?
