We do not know, since you have not said whether he is a full-time student. If he is a full-time student you can still claim him as a dependent and possibly get earned income credit, education credits, and the $500 credit for other dependents.
If he is 19 or older at the end of 2019 and is not a full-time student, you cannot claim him as a dependent anyway, unless you pay for over half his support and he had less than $4200 of income in 2019.
