None really, poker seems different enough in its own right
I will say perhaps some of my hobbies teach skills which might be applied to poker, but that is hardly limited to just poker.
For example, playing golf can teach you to brush off bad shots or unlucky bounces similar to how to mentally handle poker variance.
Another hobby example might be how my hobby of chess might help refine my perseverance to keep improving and think logically in a way similar to how one must keep improving at poker and approach certain elements of the game logically.
Nothing fits perfectly though - hobbies are each unique in their own way and nothing is exactly like poker
