I don't own the beginner box, so I'm probably not all that qualified to answer this, but since the BB is meant as an introduction to the Pathfinder RPG, I would have to say that yes, in terms of rules, everything in the BB will be in the core rules (possibly expanded and altered to fit the needs of the full rules), plus lots, lots more.
What the core rules will not provide is pawns or an adventure.

Think of the BB as a stripped down version of the Core Rulebook. The CRB is about 575 pages, the two BB books combined are about 168 pages worth of material (with a higher art to text ratio).
The BB covers the basics of what you need to understand the framework, races, classes, class abilities, skills, feats, how combat works, etc etc. The Core Rulebook contains much more of all of that stuff plus additional systems (item crafting, magic item creation, combat maneuvers, and more). It is a platform product to get you to the Core Rulebook when you are ready for more.

The core rule book does not contain creatures, though. They are in the bestiaries. And also on the rules archive : prd .
You don't precisely need the bestiary, but will probably want it sooner rather than later.
