Definitely not great or an expert at chess but I don't think you're correct. I've definitely heard that knowing that puzzles are much easier for GMs/etc because they know there is a winning move in that situation. Checking the board periodically with an engine to know the evaluation would also let you know when there is a very good move to play.
