I’m trying to understand this so I can get on with learning for school and buying my own PC components but I’m having a really hard time understanding why these are both the same but different. Please help.

Piggy backing off the other comments, lets imagine memory as a table
Lets say you’re carrying a package and just need to put it down for a second to rest. You dont need a big table for that. Dont even need to use alot of space on that table; you just put it on the corner for a moment, then you’ll pick it up and be on your way again.
Now lets imagine you’re going to a big party and you need to leave the package on the table over the course of the party, along with dozens of other packages. You’ll probably want alot more table space because the table needs to hold ALOT more packages over a longer period of time.
This is the difference between RAM and SD cards. RAM doesnt hold memory for long and it gets rewritten quickly, so it doesnt usually need to hold onto big things for very long. SD Cards hold onto memory for as long as you need it so you might need more memory if you want to store more or bigger things.
