Hey there gmarvano,
How are you doing today?
Regarding posts you should control this from your admin panel in discussion settings in Settings -> Discusiion, see screenshot https://screencast.com/t/VBZBYRVzi. This will affect the new posts, as for pages and old ones you’ll have to manually override that when editing post/page click on the “Screen Options” in the top right corner of the screen, then check Discussion and after that make sure to uncheck “Allow Comments” in the discussion metabox https://screencast.com/t/h2X9OnGjld.
Aside from that and if this doesn’t work you can simply hide it with CSS, to do that please try adding the following CSS code in the style.css file of your child theme or add it in your site using the following plugin:

section#comments {
display: none;
}
This will hide the comment form from your posts and pages.
Hope this helps ??
Cheers,
Bojan
