Yes.
There are two "deductions" a taxpayer gets, a personal exemption of $4050 and a standard deduction** of up to $6300.
When you are claimed as a dependent, you lose the $4050 exemption. You still get a standard deduction, that may be less than $6300, but cannot be more than $6300.
**Technically a taxpayer gets either a standard deduction or can itemize deductions. It's unusual for a dependent to have enough qualifying expenses for itemized deductions (examples: real estate taxes and home mortgage interest)
