Because there is no absolutely correct line of play. Bad beats are proof of this. If you know the odds and play right, both of which concepts are fuzzy, you'll have much better luck.

Professional poker players understand odds either by experience, calculation or intuition, because if they didn't they'd be dead broke. Explaining things clearly in a book is very difficult, that said, read every poker book in your chosen field and read it critically (is this true or false in my own experience? dunno is an acceptable answer), you will learn something new and useful, I always have. Even if it's "THERE I LEARNT HOW NOT TO DO IT!"
