GNOME is just as configurable as KDE. The thing is that in KDE it's available from the start (and easily accessible), while in GNOME you usually have to install extra packages or mess around in gconf.
Most beginners and average users simply want a desktop they can work on. Not everyone is interested in changing colors or widget styles. For that GNOME does a pretty good job.
