I think it's really strange that apt-get update and apt-get upgrade need sudo. But why doesn't using Software Updater need it as welll?

I mean, I can install (almost) all updates without even being sudo, making Software Updater an easier (and maybe more safe) way to update?

Because you silently authenticate via PolicyKit when running the Software Updater. Part of the 'secret' is in the file

/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

more exactly via this entry:

[Update already installed software]
Identity=unix-group:admin;unix-group:sudo
Action=org.debian.apt.upgrade-packages
ResultActive=yes
