This is a recreation of the World Cup effect or similar to it, the goal here is just to showcase how cavalry uses a system that generates these stuff easily compared to After Effects, you can see how all this animation is basically based on one rectangle or one custom shape and then all these other animation you're seeing is basically a duplicator node that's generating all that stuff With a stagger behavior and the shape offset attribute in it.
Also, you can see how it uses a local Smart folder asset to fetch the images and a custom CSV file for the team names and their scores for each team, and then you can use Cavalry Control Center to basically control these elements while the animation is running.
