Yes, your parents can claim you as long as you are not providing over half of your own support, even if you made over $5,050, since you are 19 and a college student as long as you were a full time student for at least 5 months in the year.
When you file your return you will just need to make sure you check that someone else can claim you as a dependent on their return so they're return is not rejected when they claim you. Also, if you are paying for tuition with loans, they can enter your 1098-T on their return to claim an education credit if they qualify income wise and your school/education meets the criteria to claim the credit.
The following criteria must be met to claim someone as a qualifying child:
- Your child (including adopted and foster children), your sibling, or a descendent of any of them.
- Age 18 or younger at the end of the tax year OR under 24 (and younger than you and your spouse) if they are a full-time student
- Lived with you for more than 6 months during the tax year
- They did not provide more than half of their own support (social security does not count)
- They did not file a joint return, unless it was to claim a refund
