I really don’t understand what SD card reader on MacBook Pro is for.

All small cameras and devices use micro SD. Professional cameras don’t use SD since forever now. Basically I always need an adapter now.

You can use an adapter for a micro SD but you can’t shrink the size of a normal SD card, is my only guess.

I don't think that's right, professional cameras still use full sized SD cards.
