Content Type
A content type is a collection of SharePoint site Columns (metadata fields). We can use the Single content type (reuse) for multiple lists and libraries and also we can add the workflows to the content types.
Content type Hub
Content Type Hub is a central location where you can manage and publish your content types. Once you publish the content type we can use those content types across the site collections. This is one of the best OOB feature in SharePoint.
In SharePoint Online by default ContentTypeHub is available. No need to do any configurations for Content type syndication Hub
