What you are referring to sounds more like a component library rather than actual UI patterns. To be fair, generally UI patterns are only suitable for mature or large design teams that need to manage a number of different brands and/or products.
If you look at a website like UI-Patterns.com, the contents are organized by the type of problem or interaction that the user is dealing with and some of the reusable or repeatable patterns that have been implemented to solve the design task.
Take for example Getting input from the user, there are three different contexts that may require similar or different UI components.
There are plenty of other examples but I think better clarity of the terminology would help here since pattern is more generic and abstract than a UI component. Another example is the Dark Patterns website that lists a number of user interactions that use a combination of UI components.
