Custom Page Pagination in wordpress - wordpress

Question

I have placed below function in functions.php file
if ( ! function_exists( 'post_pagination' ) ) :
function post_pagination() {
global $wp_query;
$pager = 999999999; // need an unlikely integer
echo paginate_links( array(
'base' => str_replace( $pager, '%#%', esc_url( get_pagenum_link( $pager ) ) ),
'format' => '?paged=%#%',
'current' => max( 1, get_query_var('paged') ),
'total' => $wp_query->max_num_pages
) );
}
endif;
My current page includes this code which will give me pagination based on custom query i have created. I dont get around why query_posts() is not working.
<?php
//Template Name:dummy
?>
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts(array(
'post_type' => 'page',
'paged' => $paged,
'posts_per_page' => 3,
));
if (have_rows('portfolio_listing', 117)) { /* first group */
while (have_rows('portfolio_listing', 117)) {
the_row();
if (have_rows('all', 117)) { /* second group */
while (have_rows('all', 117)) {
the_row(); ?>
<div class="col-lg-4 col-md-6 mt-lg-5">
<a href="<?= the_sub_field('page_link'); ?>" class="portfolio-wrap">
<div class="portfolio-img">
<img src="<?= the_sub_field('portfolio_image'); ?>" alt="">
</div>
<div class="portfolio-content">
<h6><?= the_sub_field('title'); ?></h6>
<h2><?= the_sub_field('content'); ?></h2>
<div>
<button class="portfolio-btn"><?= the_sub_field('btn'); ?></button>
</div>
</div>
</a>
</div>
<?php }
post_pagination();
}
}
}
?>
