No, they are not really "part of the pool". A pool apron is the surrounding area outside of the pool.
A pool apron may or may not be physically attached or even molded to the same piece of concrete as the pool it serves.
But the question you are asking is much akin to "are the stairs in front of a house, part of the house"?
Again the answer being, no not really. The house is the house, the stairs are a means to reach the house. Whether those stairs are molded into the concrete foundation or simply free standing wooden steps or bricks leading up to the house is another question entirely.
The same goes with pool aprons, there are a wide variety from molded concrete attached directly to the pool or separate aprons made from wood or brick that are simply next to the pool.
A pool in its purest form is simply the water and the container that water is in. Thus an apron is an accessory to a pool, attached or not being a separate question. A pool does not even require an apron to be a pool.
