Is Organization the same as "Groups" in gitlab?

Application version
    0.13.0+dev
Git version
    2.24.3
Go version
    go1.14.7
Build time
    2020-12-13 02:27:53 UTC
System: Debian 10

So basically I like to group my projects into groups. Should I be using Organizations to do that?
Like this:

gitlab.example.org/kubernetes-projects/gogs

In gitlab you can even create subgroups. Looking for a similar functionality in gogs.
