Using <p> tag as a container

Question

I see many people are using <p> tag as a container for <img> or even inside <form> for <input> tags, can someone please help me understand why? Couldn't they just use <div>/<article>/<section> instead?

Answer 2

I know it's a block-level element, but I needed more specifically detail why they are using a tag that's meant to be used for parameter and not using div tag which also a block-level element.
