Can my IMac be restored to Catalina after messing up a factory reset, ending up with OS X 10.9.5, if it’s possible any advice would be gratefully received, I made the mistake of following a YouTube video in order to do a factory reset.

Let's start with which exact model is your iMac? If I understand your post correctly, it is now running OS X Mavericks (10.9.5) ... correct? Finally, your goal is to upgrade it to macOS Catalina? If so, do you already have a backup as performing a "factory reset" would completely erase your Mac's system drive, before installing a "fresh" copy of Catalina.

Ok, well then I have provided you a number of links to assist you with getting your Mac back up and running. If none of them help, then the next step would be to contact Apple Support directly. To do so, simply select the "Get Support" link in the upper right-hand side of this forum's web page.
My IMac is a late 2013, it was running Catalina, my son was using it and it needed to be reset, which I tried to do but messed it up, there is no backup.
