It depends on your experience. At first, I wanted to give you links to
official documentation that would clarify situation a bit but
surprisingly I didn't find any clear and definite explanation in
official documentation on TeX Live pages (tug.org/texlive).

That is correct.

And this seems to be correct but there are subtleties.

I seriously doubt, I switched long ago from Slackware to Ubuntu but just
for a while, the reason was that I wanted "the bleeding edge", even for
TeX Live provided by distribution, so now I use Archlinux and my
distribution provides "latest" version of TeX Live, but I still use TeX
Live distribution from TUG.

Why? Because of these subtleties: TeX Live consists not only from binary
programs but a huge number of different packages, 'packages' in terms of
TeX world. Yes, the binaries are NOT updated between releases (AFAIR
there were some 'official' information that they shouldn't, but
sometimes they are updated too), but packages ARE updated continuosly,
authors upload them on CTAN, see for example archive of 'ctan-ann'
mailing list
or front page of TUG (www.tug.org, "Latest CTAN updates"), from which
they are taken into (vanilla) TeX Live and these updates are meant in
sec. 3.4.3 of TeX Live Guide

And I don't think anyone did this, even unintentionally. I think the
only purpose was to remark that there is (big) difference between TeX
Live provided by Linux distribution and vanilla TeX Live provided by
TUG. The last one uses tlmgr to manage installation, and as it is said
on page http://tug.org/texlive/distro.html

  System distributions all have their own packaging systems, so tlmgr is
  not used for TeX-related package updates by any distro that we know

so anyone that uses (vanilla) TeX Live can get any updates by means of
tlmgr tool, simply running
$ tlmgl update --self --all
$ sudo tlmgr --self --all
depending how was (vanilla) TeX Live installed (as normal user or as
administrator, for example through sudo).

While TeX Live installed by Linux distribution package manager, like
apt-get, will get updates for packages, in terms of distribution,
occasionally or on some schedule.
