Does deleting your Android apps data delete your personal files?

I use Redmi Note 3 with Android 6.0.1. Out of 10 GB internal storage, 4.5 GB is occupied only by apps. I see that app data and app cache eat up a lot of free space. I safely delete app cache data.But since that’s not enough so I want to delete my app data also. But all my files in my phone are important to me so I want to be sure that deleting my apps data won’t delete my personal files. Some of the apps whose app data I intend to delete are Google play services, Google drive, Mi Browser and Google chrome. I am not sure what files does this ‘app data’ contain and I don’t know if there’s any method to know that.
