However, while URLs allow you to locate a resource, a URI simply identifies a resource. This means that a URI is not necessarily intended as an address to get a resource. It is meant just as an identifier.

Very untrue/misleading! It doesn't simply (only) identify it. It includes URLs, so a URI may be a locator, a name, or both!
https://datatracker.ietf.org/doc/html/rfc3986 states it better and perfectly:
A URI can be further classified as a locator, a name, or both. The term "Uniform Resource Locator" (URL) refers to the subset of URIs that, in addition to identifying a resource, provide a means of locating the resource by describing its primary access mechanism (e.g., its network "location").
This means that a URI is not necessarily intended as an address to get a resource. It is meant just as an identifier.
The "is not necessarily" part is correct. The "is meant" part is incorrect; shoudl be "may only be meant as".
