A path starting with a tilde, i.e. ~/ is Unix/Linux shorthand for a user's home directory. On MacOS, /[USER]/Library path is where user installed applications place application needed files or use as information storage. Somewhere on your Mac you have an application that uses the StatusKit name (possibly this - https://statuskit.com/).

As for the specifics of the tables, that's up to the makers of the software. From description, my guess is this is some kind of contact information. Your best bet is to contact makers of software to understand what they've placed under the hood of the database.
