While studying engineering I explicitly remember my classmates being weaker and stronger at different topics, and our study group would teach the thing they were strong at.

I had a really intuitive grasp of mechanics and dynamics and free body diagrams, others were much better than me at electrical engineering concepts, others again strong in fluid dynamics etc.

There’s definitely some variation in the things people are naturally able to grasp based on their past.

So initial exposure to a new topic for the same group of people, naturally some will take to it more easily than others.

I wouldn’t say it was a cut and dry as “learning styles” but some combination of the material and the way it is presented by the professor makes it digestible to varying degrees by students.
