Sophia Yes! A real book is the same thing as a fake book. Originally, there were only fake books, which were printed in the basements of university music departments. These were created without any permission from the copyright holders, and allowed musicians to "fake" their way through a performance, without the actual sheet music. So when legal version of fake books were created, they were marketed as "Real Books". Now that real books are commonplace, the illegal versions do not have to be smuggled and copied clandestinely (though people now can easily illegally obtain real books, so are they fake again?).
I would choose an easier fake book, though, to start with. Something like this. Or if you don't have a teacher who can teach you, something like this (sorry it's out of print--I remember looking through it and thinking it was pretty good, but I'm sure there are similar beginner-level books about using fake books).
