Please answer this !!

Had a interview at Taco Bell yesterday.. the lady said that some of the answers I said worked in my favor because she liked the idea of them.. but she also said I was the only person she interviewed that didn't have any work experience..she told me she would make a decision by tomorrow (today) of who she was going to hire.. I mean the days not over and I've also read that some people get calls within 3 days . She said she would call if she wanted to hire you but if she didn't then that means she went with someone else. She was a nice lady, but I've never had a job before and I'm really bored this summer and plus I need the money to be able to get my kitten neutered. My sister and grandma told me not to call because that would have me come off as desperate and to wait until Monday to see if I get the call but if I don't then I shouldn't worry about it.. what do you guys think?? I'm so sick of going to interviews and not getting the job.. the interviewers say that j give good answers but don't hire me because I don't have any work experience.. how tf am o going to get work experience if no one wants to freaking hire me!? 😡

Edit: Sorry I couldn't wait something was telling me to call!! But when I did the other manager said that she left early and won't be back until Monday so try to call then..should I call Monday or wait until Tuesday still??
