Try this code:

// change submit button text in wordpress comment form
function wcs_change_submit_button_text( $defaults ) {
$defaults[‘label_submit’] = ‘Post Story’;
return $defaults;
}
add_filter( ‘comment_form_defaults’, ‘wcs_change_submit_button_text’ );

Add CSS, I have checked there added padding top.

Check screenshot after remove padding.
