Yes, in most cases you are considered a US Person for tax purposes if you were born in the United States, even if you have never lived there. US citizenship is generally granted at birth to anyone born in the US, regardless of where they reside or whether they hold another citizenship.
As a US Person, you may have tax reporting obligations to the US authorities. If you believe you have renounced your US citizenship or have another special circumstance, you should seek advice from a tax adviser or consult the official IRS guidance.
