I am taking a maximum of 189,000 in loans for my school (USC) with my little scholarship. Go ahead and tell me how stupid I am, that's fine, as long as you provide an answer to my following question too

Luckily, I was able to find a good place for relatively cheap (720 per month with utilities). And I spend about $50 a week max in food for myself. On that alone, based on the COL estimates, I am saving at least ~$5000 a semester.
There are some other ways I can cut costs. The only for sure thing is that I can save $15,000 for $174,000 total debt instead of the $189,000. However, is that even worth it or should I take out more money than I actually need? I'm not sure if $15,000 is really going to make a huge deal. If by G-d's grace I get a big law job, it's not going to amount to much. If I get a pubic interest job and have to pay that over 20 years, it's not going to add that much to my monthly payment is it for it to matter?
So, am i better off taking more money out than I need so I have more wiggle room after I graduate (I will probably have about 10K to my name after graduation of non-loan money, taking out more money would mean I will have that amount left over if I budget right), or should I just borrow the amount I need and hope that 10K will sustain me for a few months if I don't get a job before graduation?
Thanks, so confuzzled here haha.
