No problem! There’s a lot of card effects so it can be hard to keep track of, or even categorize sometimes. Don’t worry about memorizing cards if it gets in the way of having fun - if playing physical paper MTG, most people are reasonable enough to explain what their cards do if you ask!
The best way learn things is to build the deck you want and have fun playing with other people, and to see cool stuff people are doing.
Probably the card design categories as well, since if you know a lot of the categories you know what strategies to expect, or even build.
