The primary difference between tags and labels are the ways they are leveraged in the community.
Tags are information that users can enter to their individual posts that helps in creating a taxonomy for other users when searching for something.
Labels are a different type of method to create meta-categories for topics as a whole and are configured by the original author of a topic only. This can be used to help users that are browsing the community looking for posts on a specific overarching topic, or they can subscribe to labels if there is one that they find particularly interesting.
