Super Mario 鬥片 (Fight Piece) Set #8 (Taiwanese Toy) - 20200830B - BL09
These are hard plastic toys that come from Taiwan. The name I found for them was 鬥片 which google tells me translates to "Fight Piece". They apparently go by a few different names in Taiwan.
Here is a video of some dudes playing with the round types.
