Access is database software, used to store and...ACCESS the data stored.
it would be a good idea to learn database fundamentals, to understand what a database is and how it does what it does. there are plenty of YouTube videos that can help.
there are also many YT vids for learning Access...of varying quality.
at the end of the day, Access is not something you can "just pick up". you have to learn about databases and then learn Access.
personally, for databases, i prefer MySQL, which is free and used by tons of pro sites, but lacks a user interface, unlike Access. you can install WAMP (if you're using Windows) to get a full local setup with MySQL, Apache server, and PHP, and start programming on your own PC for free!
