Using WP_Query and getting the URL from a File in post_content

I am messing around with Wordpress and WP_Query and I am wondering how I may be able to get the URL for the file that ends up being linked when I use $post->post_content or $this_post['post_content'];

In my post I just set up there to be a file upload of a PDF with a title. No preview, no download link.

At this point I am just given a link that is similar to the PDF file name. I know I can probably just extract the link using some other function but I figured there must be some way to get to the array of the content and then just extract the entire file path, including the wp_uploads/month/day/x.pdf URL.

$press_pdfs = new WP_Query( 
    array( 
        'post_type'         => 'post', 
        'post_status'       => 'publish', 
        'posts_per_page'    => 4, 
        'category_name'     => 'press-files' 
    ) 
); 
        <?php if ( $press_pdfs->have_posts() ) : ?>
            <div class="blog-posts">
                <h3 class="news__heading">PRESS RELEASES</h3>



                <?php while ( $press_pdfs->have_posts() ) : $press_pdfs->the_post(); 
                    $postID = get_the_id(); ?>

                    <div>
                        <hr>
                            <?php 
                                $this_post = get_post($postID, ARRAY_A);
                                echo '<pre>';
                                print_r($this_post);
                                echo('hi');
                                echo '</pre>';
                                echo($this_post['post_content'];
                                echo apply_filters('the_content', $post->post_content);

                            ?>
                        <hr>
                    </div>


                    <a href="<?php echo $url; ?>" class="" target="_blank">
                        <h4 class="post-title"><?php the_title(); ?></h4>
                    </a>

                   
                <?php endwhile; ?>

            </div> 
         
        <?php endif; 
        wp_reset_postdata(); ?>

In this example this_post['post_content'] and post->post_content give me the same result, which is the link. I want to get the full URL from that link.
