WooCommerce get all products with SKU - wordpress

Question

I want to get a list of products with sku and post id with this code, everything seems fine and ok with this code :
$statuses = array('publish', 'draft');
// Args on the main query for WC_Product_Query
$args = [
'status' => $statuses,
'orderby' => 'name',
'order' => 'ASC',
'limit' => -1,
];
$vendor_products = wc_get_products($args);
$list_array = array();
foreach ($vendor_products as $key => $product) {
if ($product->get_type() == "variable") {
// Args on product variations query for a variable product using a WP_Query
$args2 = array(
'post_parent' => $product->get_id(),
'post_type' => 'product_variation',
'orderby' => array( 'menu_order' => 'ASC', 'ID' => 'ASC' ),
'fields' => 'ids',
'numberposts' => -1,
);
foreach ( get_posts( $args2 ) as $child_id ) {
// get an instance of the WC_Variation_product Object
$variation = wc_get_product( $child_id );
if ( ! $variation || ! $variation->exists() ) {
continue;
}
$list_array[] = array(
'sku' => $variation->get_sku(),
'postid' => $variation->get_id()
);
}
} else {
$list_array[] = array(
'sku' => $product->get_sku(),
'postid' => $product->get_id()
);
}
}
I have total 1660 (470 published and 1,190 drafted) products but it's just returns 501 products and i don't know why!
this is my products in woocommerce:
this is the final result of query :
this is the result of Janki's code

// Woocommerce get all products
$args = array(
'post_type' => array('product','product_variation'),
'meta_key' => '_sku',
'post_status' => array('publish','draft'),
'meta_query' => array(
array(
'key' => '_sku',
'compare' => 'EXISTS',
),
),
);
$products = new WP_Query($args);
/* using this code you can get all products */
/* this may help you to get details */
