Does a 1099-R distribution (Roth IRA) for an adult in the amount of 7k disqualify them from being claimed as a dependent?

A dependent adult relative (aunt) received a 1099-R for a Roth IRA in the amount of approximately $7,000. Besides disability, that was the only money she received for that year. Does that disqualify her from being claimed as a dependent? I'm unsure of the income definitions.
