Certainly not. You need to be more prepared than any other shot most of the time! Check the weather report. Get up extra early for the sun rise. Go the extra mile to the perfect spot. Make sure you've got a clean camera, enough card memory, correct shoes, hat and gloves. And then, that's when luck might come your way!
As my father always always says: the right moment appears like a snail and disappears with the speed of lightning. 😉
