TYPO3 has a steep learning curve, means: in the beginning there is a lot of unknown things and you need to learn much until you get your first working results.
If you want an easy way to have a working website you could install one of the packages which provide all.
One of the easiest probably is the bootstrap package (
composer req bk2k/bootstrap-package) which
should result in a ready to use configuration where you can start to fill your website with content.
With the introduction package (
composer req typo3/cms-introduction) you will get a full installation, including content to study the mechanisms of TYPO3. (But you are not allowed to build your public website from it)
