Yes, that is correct, this is the basic 5 paragraph small essay structure:

Intro paragraph - I am going to say blah blah.

Body paragraphs (usually 3, can be more) - each particular point of blah blah, explained in a self contained manner, that doesn't reference or build upon anything in the other body paragraphs.

Conclusion paragraph - I said blah blah.

This is a writing style typically taught to middle schoolers, 20 years ago, before we spent 20 years passing every failing student onto the next grade becauase otherwise the school will shut down.

It is meant to be an introduction to the concept of writing in a longer form than just answering a single question with basically one paragraph.

It is not meant to be good, compelling, moving or engaging writing... it is meant to be the bridge between basic and intermediate levels of literacy, to give young humans more practice with stringing more sentences together.

Writing in this manner almost always can be boiled down to maybe a couple of sentences, basically you could just rewrite the conclusion with a bit more detail, and there ya go.
