I’m a different person than you replied to. You are both correct.

When we, Americans, vote for president we vote for an individual by their name on the ballot. Technically, we’re voting for electors who have been chosen by our candidate. Those electors get to vote for the actual presidency and can technically change their vote (relative to the popular vote), but in many places they would be penalized for doing so. To my knowledge there have been few, possibly no, legal cases which have tested these laws or systems. So in practicality it doesn’t matter.
