Click one one of these folders and have a look at the permissions rules in the 
Get Info window. You'll find that while generally ownership of the folders will 
be assigned to "System" with read and write permissions, everyone else will 
have at least read permissions, which means everyone else has access to the 
folders: they just can't change their contents. Bear in mind that all this 
changed with the introduction of Mac OS X. Prior to that, Mac OS didn't really 
care where anything was, since it was a single-user system, ie you could not 
add different user accounts. In Mac OS X, everything that you want to belong to 
you must be kept inside your own account folder, ie, home.

All you need to do is to move all your "private" stuff into your Documents 
folder. No one can get to them then.
