I am a full-time 20y/o student preparing taxes for the first time. Am I required to say that someone else can claim me as dependent on their tax return?

As the title says, I'm a 20y/o full-time student. I am able to provide over half of my own support (with earned income). Can I answer "no" to "Someone else can claim me as a dependent on their tax return?" My parents will not be claiming me this year.
