Okay, so with no avatar there is no text.
Not sure why you think that. Hopefully not because I added some red text (and a couple of underlines) to the image to explain where the text will be displayed.
If you have any text in the "Personal Text" box, it will be displayed just below where an avatar would be.
Have to upload one.
Definitely not correct. Just choose one from the "Gallery" or don't use anything.
I think it might be easier to understand if you just visit the Profile page.
One of the fun things to do with any app or web page is to investigate any menus. It may be surprising when you can discover what you can do with an app or what might be available on a web site. It's rather like reading a (usually) non-fiction book; there are usually lots of things to discover in the table of contents, indexes, notes, sources and appendices.
