No. In order for them to claim you, after age 18, you would have to be a full time student and still living with them.
There are two types of dependents, "Qualifying Children"(QC) and
other ("Qualifying Relative" in IRS parlance even though they don't
have to actually be related). There is no income limit for a QC but there is an
age limit, which is raised for full time students. Only a QC qualifies a parent for the Earned Income Credit. They are
interrelated but the rules are different
for each.
Because you are neither a FT student or under 19, the income test applies and you made more than the $4000 allowed.
