It prefaces with "WordPress is well-known for its ease of installation." And I believe this, until reading the fourth step in the installation process:
"Be prepared with a secure password for your Secret Key"
Wondering what that is, I follow the link. It takes me to this:
"As part of the WordPress installation, you must modify the wp-config.php file to define the WordPress configuration settings required to access your MySQL database."
And this is a totally necessary part of the installation process, which starkly contrasts the first statement about WordPress known for being easy to install.
Further reading provided me with this information:
"If you are using a hosting provider, you may already have a WordPress database set up for you, or there may be an automated setup solution to do so. Check your hosting provider's support pages or your control panel for clues about whether or not you'll need to create one manually."
So clearly, this can be done. But I wish they'd take it back, that part about being "easy to install."
