No. There are a lot more data blocks than inodes. A likely ratio is about 20 to 1.

You can use debugfs, ext3grep, and several other tools in tct/tsk to see a lot of the basic stats about your file system (block size, inode size, etc.)

In Linux, an "inode" is basically the representation of "a single file." The name is historical. Directories, in turn, associate names with those inodes.
