No worries, thanks for asking this!
The idea behind the theme is that you'll use a specific mechanic as an inspiration for your jam project.
But don't worry tho - all I can say is that there will be plenty of mechanic options!
Let me know what you think of this approach - in a certain way we all are inspired by mechanics from other games when building the jam project.
Hopefully that can even help to give direction to those that are starting development / jams! :D

My name is Gabriel, well, I've been looking to join a Jam lately, but I know my limitations and I kind of know that my forte is the programming and mechanics application, but ... I wanted a team to be able to create together something cool in this Jam, can the creator or someone help me find a cool team? I am Brazilian and here if it is to create something, like a game in Jam, only in universities.
