Yes, a good tent with fly should keep you dry, in normal rainy conditions. Obviously some tents aren't so good, and sometimes rain can be severe and long lasting, and have a lot of wind with it. In these cases, a tarp over the tent can be useful.

I own a really good tent (a older North Face VE 24). It is a bit heavy for backpacking but provides excellent shelter. I use it a lot on sea kayak trips. With the VE 24 I rarely if ever have put a tarp over the main part of the tent. However, I often rig a tarp up over the entrance to the tent. This provides a sort of front porch, where one can take off wet rain gear and boots before entering the tent. In sustained wet weather I have found that works really well in keeping the inside dry.
