Answer 1

<referenceBlock name="catalog_product_gallery">
    <action method="setTemplate">
        <argument name="template" xsi:type="string">Xyaddons_Productzoom::produtc/image.phtml</argument>
    </action>
</referenceBlock>

Answer 2

In your function, Template path spelling mistake.

public function beforeToHtml(\Magento\Catalog\Block\Product\Gallery $originalBlock) {       
        $originalBlock->setTemplate('Xyaddons_Productzoom::produtc/image.phtml');
    }

check directory path spelling mistake produtc/image.phtml instead of product/image.phtml.

Check folder name with product not produtc and try again.

Moreover, you have to define the plugin in the di.xml file of your module

<type name="\Magento\Catalog\Block\Product\Gallery">
    <plugin name="xyaddons-productzoom-product-gallery" type="Xyaddons\Productzoom\Block\Product\View\Gallery" sortOrder="10"/>
</type>

Thanks.
