You should tell your parent, respectfully, of course, that they should start reading up about the requirements for an Ivy admissions. As it is, they seem to have at least one unsupported and incorrect assumption, and may have more. The more they know, as opposed to assume, based on what somebody told them, the better they can help you find a college where you will thrive.
Being in the top 1% of your class is an amazing ranking for an Ivy. Keep up the good work.
As an aside - while you should do as well as you can in school, and aiming at achieving Ivy worthy stats is a good way to ensure this, don’t build your entire school future for the sole purpose of “getting into an Ivy”. The name of your undergraduate school is such a small part of your life, so don’t make it your entire focus throughout high school.
