Question regarding claiming parents as dependents for 2025 Taxes

Hello, I have a question regarding claiming my parents as dependents. I am currently providing residence and other necessities as they don't have income. For the year 2025, my dad withdrew about $16,000 from his Traditional IRA and closed the account. I understand if they have earned income of over $5,200, I can not claim them as dependents. Since the income is from traditional IRA, does it still count as earned income? Also if that count as an earned income, and my parents file taxes as married filing separate, can I at least claim my mom as a dependent? Thank you in advance!
