Differences between <section> and <article> tag

The "section" is more generic. According to my favorite reference, MDN, the <section> element:

...represents a standalone section — which doesn't have a more specific semantic element to represent it — contained within an HTML document. Typically, but not always, sections have a heading.

And the <article> element:

...represents a self-contained composition in a document, page, application, or site, which is intended to be independently distributable or reusable (e.g., in syndication). Examples include: a forum post, a magazine or newspaper article, or a blog entry.

Check the actual MDN pages (linked) for more details.

Thank You,

Regarding "section" it is used to group similar content. For instance, we may have a sport section in a news chanel, inside sport section we may have divided into smaller sections for:1)Basketball, Football,3)Voleyball etc

While "article" is considered an indepedantable part of the site that represent a specific topic about,

For instance in a news channel, an article will be considered an analysis of previous day basketball game between 2 teams. Its a specific analysis of how one team defeat the 2nd team - and thats all

While in a "section" is more broader concept,

Mention if am correct about the above,

Can we use an <article> tag inside a <section> tag or vice versa?
