The CFG which accepts deterministic PDA accepts non-deterministic PDAs as well. Similarly, there are some CFGs which can be accepted only by NPDA and not by DPDA. Thus NPDA is more powerful than DPDA.

"In the theory of computation, a branch of theoretical computer science, a pushdown automaton (PDA) is a type of automaton that employs a stack. Pushdown automata are used in theories about what can be computed by machines. They are more capable than finite-state machines but less capable than Turing machines (see below).

WebIn a nutshell: This idea that a non-deterministic automaton can guess (or be helped by an oracle) is directly related to our existential interpretation of non-determinism. Another interpretation is possible (maybe others) where "guessing" would not make sense. Non determinism is strange.
