Chen Qi has already given you pointers to the documentation. Though,
I'll just add a few remarks that hopefully will kickstart your
understadning when reading the docs.

No, the recipes themselves do not enforce their own inclusions into your
image. (That wouldn't really make sense, especially not when including
such a large layer as meta-oe).

Which image are you building? 

Say that you're building core-image-sato, then you'll have to look at
that recipe meta/recipes-sato/images/core-image-sato.bb. 

There you might find IMAGE_INSTALL, which defines what packages (and
package groupds) this recipe wants to install. 

The recipes can also define IMAGE_FEATURES, which are used by the
core-image.bbclass (which is inherited in the .bb-file), to add a number
of packages.

Sure, there's likely some stuff in most images that you're not
interested in. All the supplied images are there for some use-case, be
it demoing stuff, test, etc.

If you want to customize an image more, I'd recommend you to create your
own image. A first step might be to just copy one of the image recipes
to a layer of your own, and then modify it according to your taste.

Cheers,
Anders
