Yes WordPress is under the umbrella of Automattic to be specific.
Yes, you would need AMP HTML (tags), AMP Javascript, etc. It is a different setup than normal web pages as referenced in the article you shared. AMP is not part of the W3C standards unless I'm mistaken and those tags and additional markup are now recognized.

You would not need AMP tags for a normal website. You can have a very fast website without using AMP separate markup.

Simply because a web browser can read AMP markup doesn't mean it is adhering to web standards. It still requires more time to make a website with AMP in addition to a normal website. That was the original point of the W3C standardization for markup.
