How to hide a block if there are more than 3 entries?

Question

PHP

Hello.
There is a block.
In which two arrays are displayed, one displays the entries attached to the "Curators" entry, and the latest entries "Upcoming events"

There is not much space for the block, and I came up with the idea to do such a thing.
So that if there are more than 3 curators, then the "Upcoming events" block will have to disappear.
How to make this?

My code on curated block output

<div class="kuratori">
<?php
$posts = get_field('lektori');
if ($posts) { ?>  
<h2>Кураторы</h2>  
    <?php foreach($posts as $post) { setup_postdata($post); ?>

<div class="meropriyatiya">
<?php 
$params = array('post_status' => 'future','post__not_in' => array($post->ID),);$the_query = new WP_Query($params); ?>
 <?php while  ($the_query->have_posts() ) : $the_query->the_post(); ?>

You need to wrap the block of events in a condition. If I'm not mistaken it should be like this:

if (count($posts) < 3) {
 // блок мероприятий
}
