Hidden tables

Greetings,
I was wondering, if I am about to create a report in powerBI desktop, and I import several tables (from MS Azure in my case) and while doing my report lets suppose I hide a few tables because I don't need them. When I finally create the needed dashboard and upload it, will these hidden tables later update with new data as well? I am considering this question because of the limit for the free version users which is 1GB.

Thank you!
