Knowledge and skill dont go hand in hand.
they need to but often dont.
someone could have a high degree of skill in coding for example but not have a clue how to cause a buffer overflow in the linux kernal.

The same to in reverse. Someone could know exactly how to overflow the kernal but doesn't have the coding skill to exploit it.

These 14 y.o lamers are usually the kinda ppl who have stumbled accross a hacking site and are looking for the quick and easy way so they can show off to their friends by crashing a website.
they will use a tool that was often made by someone with the knowedge and skill to discover an exploit and abuse it thereby giving the people who are out there discovering and reporting security holes a bad name.

sorry bout my little rant but i feel quite strongly about lamers.
I've gotten in trouble coz of them before (im happy to give you details if ur interested)
