I dont know how to start saving and budgeting

I'm a california community college student, and i have around 9k in my checkings account.

I work on the weekends, making around $450-60 biweekly

I Have no savings account so im not sure how much to into it.

I live with my parents

I dont have any plans on buying something like a car, but i will be buying a new mac and ipad for school next month because my laptop super old and falling apart.

Also my family uses bank of america… should be using a different bank?

I'm not knowledgable about this stuff, I come from a very low income family 🙁 I really want to start somewhere.
