The usage of SEO entities is not considered a factor in the ranking of a page. They do help in resolving ambiguities about what the page is about, or where it should show up. Once that is established other algos such as E-E-A-T rank the document from the available list.
Take for example a search for: "Great Dane" is an entity which is also a type of "Dog" another entity, Eat is synomous with the entity "Diet", and "Chocolate" is an entity. By looking at the pages that exist in all of these entities a list of pages can be created. E-E-A-T will rank these pages based on who is the most knowlegdable and trust worthy. This list can be further refined by exact match of the terms.
Image is an exhibit from the recent legal cases faced by Google.
Also added into the mix is gain of information, this can be applied after the results are constructed for use on a new search. "Posioness," and "Vet" would be discovered entities from the list of pages that would provide a gain of information. The Gain of information algo is applied after a search to refine the search. Additional information available is how people interact with the result in search. There is no real understanding of the question nor does there need to be, it is only information retrieval.
Another Exhibit
Entities with Ipsum Lorem on the Rest of the Page
For search or document Retrieval the entities, (things, people, places, et la), are important words. Most of the other text could just as well be Ipsum Lorem, and in fact, many have tested Ipsum Lorem pages with keyword entities placed in important locations on the page. Yes, the rest of the words are important but they add details to, (let us say the scene where the entities exist), which don't identify the main subject or the (search entities, keywords, index term) of the content.
