two things; there are packages, and packages must be in a format. A package manager is a program (...maybe a suite of programs...) which has to understand the format of the package(s) that you intend to use (and stuff about which libraries are already available, etc, etc).
So debian, and pretty much everything directly descended from it, uses the .deb format and the programs on that platform understand that. It used to be that the only other format that was in popular use was RPM (originally the Redhat package manager, but now the RPM Package Manager, apparently) but now there are a few others with 'small market shares'.
Most package managers only understand one format, but there was something called SMART (& there may be others) which tried to be cross-platform; haven't heard of any development on that recently, though.
One confusion that is often made is that the format
and the package manager
are not the same thing (particularly on RH-like platforms where you can use the RPM command line utility to manipulate RPM packages); the manager has to understand the format, but they are not the same thing.
So, to your original question, the utils that the *bunutus have from debian work on pretty much any debian-derived platform, but not on the RPM platforms or the other smaller ones.
