Use "exact" comparison because otherwise it will be compared by casting types to 0 or false and it will show you misleading records

change the if to

if (substr(get_the_title(), 0, 3) === '000') {

pay attention there are three =

How to apply your filter at edit time using https://codex.wordpress.org/Plugin_API/Filter_Reference/wp_insert_post_data

function my_wp_insert_post_data_filter( $data )
{
  if( substr( $data['post_title'], 0, 3 ) == '000' )
  {
    $data['post_title'] = 'test 1';
  }
  else
  {
    $data['post_title'] = 'none';
  }
  return $data;
}

add_filter( 'wp_insert_post_data', 'my_wp_insert_post_data_filter' );

You should use get_the_title(). the_title() will print the title to the screen. In your case, you need to return the title so that you can parse it.

$verify = get_the_title();

If you want to use the_title(), you can, but you will need to specify that you want the value returned.

$verify = the_title('', '', false);
