When sorting product lists should the ordered list always have a section title or label?

I am working an applying filters & sort options to a product list. Each product displayed has a number of attributes which are displayed within a card layout. one of the attributes is product type. While filtering applies a hard boundary removing certain products from the list, sort order dictates the sequence in which the products are going to be displayed. hence my question:

If each product also shows which category it belongs to for example ( sport) is it necessary to have a section header providing the same information? Bearing in mind that users are able to see from filtering and sorting options default values how products are listed.
