Yup, and the only people who are not subject to the jurisdiction of the U.S. are indians with tribal affiliations and ambassadors and their staff.
Claiming that someone whose parents were foreign citizens is not subject to the jurisdiction of the U.S. leads to the ludicrous result that such a person could not be arrested, tried, and if convicted, fined or imprisoned for committing any crime; the only remedy available to the U.S. would be expulsion.
So, people who claim that newborns whose parents are citizens of another country at the time of birth are not subject to the jurisdiction of the U.S. are effectively claiming that the U.S. has no power or authority to arrest those parents for DUI, or robbery, or arson, or fraud, or any of the other innumerable crimes for which ordinary private individuals can normally be arrested, tried, and punished.
That is a far more ludicrous result than the result that, because exclusionary immigration policies had not yet become standard in the U.S., the drafters of the Fourteenth Amendment excluded only Indians and Ambassadors.
