Two table column has a common column name is entity_pk_value. Try following way:

public function getRatingSummeryByAttribute($currentProductId)
{
    $attributesValues = $this->ratingColFactory->create()
        ->addFieldToSelect('rating_id')
        ->addFieldToSelect('rating_code')
        ->getData();
    if ($attributesValues)
    {
        $totalRatingRecord = $this->_ratingFactory
            ->addFieldToFilter ('main_table.entity_pk_value', $currentProductId);
        $totalRatingRecord->getSelect()
            ->columns('SUM(value) as sum_vales')
            ->columns('count(rating_id) as total_rating')
            ->group('rating_id')->join(
                [
                    'review' => 'review'
                ],
                "main_table.review_id = review.review_id"
            )->where('status_id = 1')
        ;
echo $totalRatingRecord->getSelect()->__toString();

And query

SELECT main_table.*, SUM(value) AS sum_vales, count(rating_id) AS total_rating FROM rating_option_vote AS main_table INNER JOIN review ON main_table.review_id = review.review_id WHERE (main_table.entity_pk_value = '14') AND (status_id = 1) GROUP BY rating_id
