No, your parents cannot claim you as a dependent. If you are over the age of 18, not a full time student under the age of 24 and you have gross income for the year of $4,050 or more then no one can claim you as a dependent.
Since you are not a full time student under the age of 24 then you would not be eligible to be claimed as a dependent under the Qualifying Child rules. You could only be claimed as a dependent under the Qualifying Relative rules. One of the main QR rules is that your gross income had to be under $4,050.
To be a Qualifying Relative -
1. The person cannot be your qualifying child or the qualifying child of any other taxpayer. A child is not the qualifying child of any other taxpayer if the child's parent (or any other person for whom the child is defined as a qualifying child) is not required to file an income tax return or files an income tax return only to get a refund on income tax withheld.
2. The person either (a) must be related to you or (b) must live with you all year as a member of your household.
3. The person's gross income for the year must be less than $4,050 (social security does not count) in 2017
4. You must provide more than half of the person's total support for the year.
5. The person must be a U.S. citizen or a U.S., Canada, or Mexico resident for some part of the year.
6. The person must not file a joint return with their spouse.
