Simple. There is a circular gasket for each spark plug between located between the valve cover and the engine. If they are not properly sealed, the oil from the top of engine will leak out of the valve cover and pool into the spark plug sockets. You must remove the oil BEFORE you remove the spark plugs. Anyway, the fix is purchase and install a new valve cover gasket and spark plug gaskets and use a gasket sealant.
Piston rings shot.
No, but burning oil will give you bad spark plugs.
Oil on the outside of the spark plugs is caused by a leaking valve cover gasket. Replace the valve cover gasket. Oil on the electrode of the spark plugs indicates the engine is worn and is burning oil. The only fix for this is an engine rebuild.
Worn down piston rings will allow the oil to seep up into top chamber where the spark plugs are. Otherwise, you just have too much oil in your crankcase.

Oil on the top of the plug would be do to a gasket or seal failure. Oil on the bottom of the plug would be do to a serious internal engine failure.
