In any Linuxsystem a process has very little to do with a program/package. Most of them are actually threads of a program, any given program can use any number of these threads to process stuff "concurrently".
If you run top in xterm look at the %CPU row and you'll see, that even the top most process doesn't use much cpu at all, and most likely it's top itself if nothing else is running.

If you're new to all this and don't really see the connection i'm trying to draw for you, don't worry and maybe just take the word from ppl running some kind of Linux every day. This is a totally typical process count, nothing to worry about at all, the only thing that's relevant, is if the processes use %cpu.
