I have referred this link i.e Product page Review Section from tabs to Bottom of page and followed the same. I also got the same result.
vendor\magento\theme-frontend-luma\Magento_Theme\layout\default.xml
I added below code :
<referenceBlock name="reviews.tab" remove="true" />
<referenceContainer name="content">
<container name="new_space" htmlTag="div" htmlClass="container" after="-">
<block class="Magento\Review\Block\Product\View\ListView" name="product.info.product_additional_data" as="product_additional_data" template="product/view/list.phtml" />
</container>
</referenceContainer>

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">

<module name="Magento_Catalog"/>
</sequence>
</module>
</config>

<page layout="1column" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

<move element="reviews.tab" destination="content" after="-"/>

</page>
