To override or re-writing the magento core or any other module class you have to create your own module and use "preferences". You can check this blog post for detail and understand how to write module to override core class. In this blog post , Below block is important to understand:

<preference for="Magento\Catalog\Helper\Product" type="FME\Test\Helper\Rewrite\Product" / >

Is main thing to understand, this part does the magic. Where tells magento which class "for" to override with what class "type".

Hope this will help.
