Debian versions

[Alan Serrano Peña]

Good afternoon, I have a question about Debian versions. Is there a commercial 
version of Debian? Any version with technical support? I was reading on the 
website that there is a version called Debian LTS, specifically Debian 10 
"Buster," but I'm not sure if this version meets what I'm asking for. I hope 
you can help me or even explain a little more about LTS and the "Buster" 
version.
 
I hope you can assist me as I don't have much knowledge about this operating 
system
