Being 100% honest, I was of the opinion that because of tipping in America, waiters/waitresses stand a chance to make $150-$300+ whereas in Europe, you probably make less than that.
You checked for France on the statistical bureau website ( INSEE )
Average Net salary is 1558 euros / month, calculated from 196k salaries. Figures are from 2021.
With that you get unemployment, retirement and healthcare. It can be considered "play money" if you are sorta careless.
Not great, but you can definitely lives on that and find lodging. ( In Paris that will be a flatshare )
