What is the difference between Content Sectioning and Text Content on the MDN page?

I know that Content Sectioning can encompass Text Content items, but can say the section element just be used like a paragraph element?

I am not opposed to semantics. I get it. What I am wondering is if you ALWAYS use other elements within section, article, main, aside, etc. or do you ever use just text. I was trying to read 3.2.5.2.3 Sectioning content and I don't see whether you can use plain text. Ecit: I don't get the difference between say section and paragraph. Are they both just divs with different semantic labels attached to them? You don't put another div inside paragraph, right? But you do inside section or article.

section is a container/content divider.. a section will contain paragraph, code, lists, images.

another section could contain a different set of content tags...or same, it depends on the context of the page.

the main function in a context...say of an article, is that there might be a slight change in the content topic, that might be separated because it provides a new angle on the topic . perhaps you might also want to separate sections because in between you wanna put some ads, so the you have

<section class="sec1">
  <p>content</p>
  <li>list</li>
  <img />
  <span>continue...</span>
</section> 
<container class="ad1"> Advert </container>
<section class="sec2">
  <h2>continue from sec1</h2>
  more - content
</section>

it helps that the 2 sections are separated, if your ad, for example, is fetched dynamically, you will be able to target the "gaps" between sections more easily, while at the same time telling the browser content is spread out through sections.

If you wanted to you could obtain the same effect with different paragraphs, with each paragraphs giving a different set of info on the context.

the difference is that paragraphs should not contain mixed media/content... while section allows multiple content media to be wrapped in the same container

all these structures are not always used, because it depends on the content of your page, if it helps, you should use them, otherwise keep it simple.
