Update the code of

/Block/Reviews.php

with below and give a try.

<?php
namespace Training\Reviews\Block;
use Training\Reviews\Model\ResourceModel\Reviews\Collection;

use Magento\Framework\View\Element\Template;

class Reviews extends \Magento\Framework\View\Element\Template
{

    public function _prepareLayout()
    {
        $this->pageConfig->getTitle()->set(__('Users Reviews'));

        return parent::_prepareLayout();
    }

    protected $_productCollectionFactory;
    protected $_productVisibility;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Training\Reviews\Model\ResourceModel\Reviews\CollectionFactory 
    $productCollectionFactory,
        array $data = []
    ) {
        $this->_productCollectionFactory = $productCollectionFactory;

        parent::__construct($context, $data);
    }

    public function getProductCollection()
    {
        $collection = $this->_productCollectionFactory->create();
        $collection->addFieldToFilter('result', ['like' => '%test%']);
        return $collection;
    }
 }

You can add $collection->count() function if you want.
