If you're using Odin to flash a stock ROM it will not affect your saved files but it's always a good practice to back up everything. Phone storage media and microSD card media just are not reliable as long-term storage so set up a back up solution now. Don't put this off, it needs to be done. Also, flashing a ROM on your S3 is something of a delicate task so while your saved data should be OK it's still a big risk.
But getting back to your query, the storage media in your S3 is divided into different partitions, most are dedicated to the operating system (Android) and one is set aside as a general user data partition. All your files and apps you install get saved to this data partition. So you've got essentially two separate sections -- the various system-related partitions that you typically only have very limited access to, and the data partition, where all your stuff reside.
Note that a Factory Reset only affects that data partition, it does nothing to the system partitions, and contrarily flashing a stock ROM will only affect those system partitions and, as long as you can follow instructions properly, it does not affect that data partition. So when you're setting up Odin to flash a stock ROM, just be sure to follow directions. (Emphasis on 'stock' as a custom, third-party ROM involves a different set of procedures).
