I'd say it depends who I'm against but overall yeah. There's always something to be learning in that game and if someone completely new to the game finds a novel way around a challenge than I'll tuck that away in my toolbelt as well. I also have to know some really obscure parts of how things work together to orchestrate the kind of board state I'm talking about so lots of research goes into it.

I actually do this mostly as a way to learn about new people; see how they approach problem solving and how they socially interact with me (MTG is a space I'm comfortable in so I end up talking way more than usual during play); but I have a couple close friends we mostly try and out shitpost each other with ridiculous gameplay. And then sometimes, on a rare occasion if someone is rude to me, I can take off the training wheels and use my finely tuned bullshittery to make them pick up their ball and go home lol
