Not really the same. The difference between the Arabian dialects and standard arabic is the same as, if not even superior to the difference between Scottish English and the queen's English . If you learn a language and then go to the people that are supposedly it's native speakers but you can't understand more than half of what they're saying is it the same language ? Even worse , you visited another country of native speakers and they speak another form of Arabic different to the one the first people you visited. Heck, Tunisia dialect literally use the feminine you to refer to a male and vice versa and it's the least jarring difference I can think of.
