Not necessarily. It depends on your content and what you are promoting. There is never harm in trying out new formats.
From our experience carousel pins do not work that well for bloggers (as video & idea pins seem to perform better for blogs), but they seem to perform very well for product-based owners.
Nevertheless, you should always keep in mind that the content format is only the cherry on the top of your cake. The baseline for good performing pins is their content which should be your number one priority.
