Is it beneficial to me to not have my parents claim me on their taxes anymore. i am 19 and a full time college student. they don't get the child tax credit anymore

The restriction on students, under age 24, claiming the refundable portion of the American Opportunity Tuition Credit (AOTC) does not apply if neither of your parents is still living.

The TurboTax (TT) personal info interview, on your return, will ask about their status after it detects that you are a full time student under age 24. When you answer that they are not living, TT will allow you to claim the AOTC.
