First you need to make sure that you are on a Gold Home package or higher. WordPress and requires a database, the first package that comes with a database is a Gold Home package. If you already on a package that allows a database, to resolve this issue you need to uninstall WordPress and login to cPanel to delete the databases that are stored there. In cPanel, scroll down to Databases, select MySQL Databases. You need to delete the database and users to start from scratch. Once you have deleted the databases and uninstalled Wordpress you should try running the installation again. If you are installing the latest version of Wordpress, I would suggest that you do it through cPanel. To install WordPress through cPanel, on the main cPanel screen, scroll all the way down to Softaculous Apps Installer. Once you are in Softaculous you will see WordPress and other CMS's. Click on WordPress and install it from there. Everything else will be created for you! The installation is also quick, it literally takes a few seconds, and you will be able to login the back-end of WordPress to start building your site.
