No, it isn't a good beginner drone. Do like some others have suggested. Get an inexpensive drone to learn on so that you have some basics when the Mavic arrives. In fact, let the Mavic sit awhile if you don't feel comfortable risking $1000 or more on you doing it right. Don't try to fly it until you are ready and feel comfortable controlling a beginner drone.
I think the Phantom is a much better learning piece. It will show you what GPS and IMU do for you, and at the same time let you turn off the GPS positioning and learn how to fly ATTI mode. For whatever reason, they don't give us control of that on the Mavic at this time, even though we've begged for it. If the GPS malfunctions, the Mavic can switch right in the middle of your doing something critical and you need to know how to handle it if it happens.
The Mavic has a LOT of features available. Every one of them can fail. The more complex the software and firmware, the more places it can fail. A Phantom has fewer features, therefore less program code that can go wrong causing you to lose control.
I'm not suggesting you don't get the Mavic. What I would really recommend though is to get a cheapie learning drone and maybe a used Phantom 3 (they are no longer available new) to learn on. You will crash. The desire is to get most of that out of the way with the cheaper $50 drone and then move up to the more complex P3 to learn more sophisticated flying. After you learn the basics, have crashed several times, and have an idea of how to fly safely, order that Mavic and very slowly work your way up with it in beginner mode and further as you are more proficient.
Despite what some people say above, learning reverse control for when the drone is coming toward you can be quite difficult. I've flown several model aircraft over the years and have never gotten where I can trust myself to go the right direction when it is coming at me. Some people learn and don't have a problem with it, but some do have trouble and never get good at it. I've crashed every airplane I ever flew toward me.
Do keep in mind that the gimbal/camera assemblies are the weak/fragile items on the drone. It doesn't take much of a hit or drop from the sky to do a few hundred dollars worth of damage.
If you get the Mavic, get DJI Care (within 48 hours of registration) so you will be covered when you do crash. Obey all of the regulations for your country, and always think about what can go wrong and what you'll do if it does. This is no different than flying a real airplane. You have to train yourself to handle anything that happens. Stay away from people, etc.
A commercial pilot didn't learn to fly in a 747.
