The same data on all pages of pager - drupal

Question

I wrote a pagination in my custom module, but the pager displays the same data on all its pages. My query has 4 elements. I want to display 2 elements per page. I use range(0,4) and it shows me all 4 elements on every page, I tried lots of combinations of range(). How can I display 2 elements per page? Please help :) My code:
public function news() {
$query = $this->entityTypeManager
->getListBuilder('node')
->getStorage()
->getQuery();
$query->condition('type', 'aktualnosc');
$query->condition('status', 1);
$result = $query->range(0, 4)->execute();
$nodes = $this->entityTypeManager->getStorage('node')->loadMultiple($result);
pager_default_initialize(count($result), 2);
$render = [];
$render[] = [
'#theme' => 'news',
'#results' => $nodes,
'#type' => 'remote'
];
$render[] = [
'#type' => 'pager',
'#quantity' => 2
];
return $render;
}

You made a tiny mistake, you always ::range() from 0 to 4 elements. Instead, you should use the ::pager() method instead.
Here is the same function as yours but using the pager instead of range.
public function news() {
$query = $this->entityTypeManager
->getListBuilder('node')
->getStorage()
->getQuery();
$query->condition('type', 'aktualnosc');
$query->condition('status', 1);
// Get all the aktualnosc nodes to initialize our pager.
$nids = $query->execute();
pager_default_initialize(count($nids), 2);
$query->pager($limit);
// Fetch nodes based on our pager.
$nids = $query->execute();
$nodes = $this->entityTypeManager->getStorage('node')->loadMultiple($nids);
$render = [];
$render[] = [
'#theme' => 'news',
'#results' => $nodes,
'#type' => 'remote'
];
$render[] = [
'#type' => 'pager',
'#quantity' => 2
];
return $render;
}
