Font – a set of characters of a certain size and pattern, intended for reuse many times and in any order.
Lettering is not a font. Lettering is a one-of-a-kind letter made (drawn, cut) for one specific situation. Many people call a font anything if there are several letters. However, often what they see is lettering. Its main difference is the emphasis on the graphic component: unique forms that combine with each other in a particular word or phrase.
The difference can be seen on the motivational posters from the site blck.ink

A headset is not a font
Back in 1898, Morris Fuller Benton, working as a lead artist in the American company “American Typefounders”, introduced the concept of “headset”. More than a century has passed, and the vast majority of people do not know what the difference is.
A typeface is a set of fonts, united by stylistic unity and consisting of a certain set of typographic characters. Each headset must have its own name.
The headset usually contains alphanumeric and punctuation marks and special characters. There are also headsets that consist entirely of non-alphabetic symbols, such as those containing mathematical or cartographic symbols.
A font is a drawing in graphics, a set of letters and signs, which together represent a coherent system, both in stylized and compositional terms.
