How do I rewrite the way my view rows are displayed
Did you override view ?? If your not override view Please follow below views view suggestion - 

views-view-fields--(yourviewmachinename).html.twig 
views-view-unformatted--(yourviewmachinename).html.twig

Note - In views-view-fields--(yourviewmachinename).html.twig,file render your fields which are present in that view Eg. If will have field - title follow below render 

{{ fields.title.content }}

Note - If your rendering page title then render {{ label }}

In these file - views-view-unformatted--(yourviewmachinename).html.twig - You will get loop here,don't change here any think.

Hope, this will help you.thanks!
