"Other systems" you mention I bet are Debian and its clones (Ubuntu being one of them). These systems have different update philosophy than that of RedHat Enterprise Linux (and hence what CentOS is, which is derived from RHEL). Namely, these "other systems" do constant micro-upgrades of components installed on the system to latest release, whenever new release of given piece of software happens. To the contrary, RHEL mostly backports important security fixes to a version that was included in original system release (but occasionally does make upgrades). Hence the differences: 1. Debian (and clones): you keep the components of the system pretty much on the level of latest release of each of components. Therefore "upgrade" to new release of the system is pretty close to just a regular routine update. This apparent advantage comes with a disadvantage, namely: every update has a potential to break something on your machine, as new release may have different internals, then you will need to work on migration to them, and this can come as a surprise with any of routine updates.
This is so flat out wrong that I don't know where to begin, and this is not the place to give a lecture about Debian stable or Ubuntu LTS release process anyway.
Not knowing something is perfectly normal and it is nothing to be ashamed of, spreading misinformation about a topic you have no knowledge of and doing it in a public list *and* when nobody asked you about it, on the other hand...
