Your definition is wrong. A PDA is non-deterministic if in some state there are several possible transitions. It doesn't matter if that applies to a transition to a final state. Your example is deterministic. Check: From state q 0 with Z 0 on the stack, on reading a there is one possibility. In the same case there is no alternative on input ϵ. sporteltern toolbox
