How important are hooks for ivy league colleges?

Thanks for the responses

To my surprise, alot of people are commenting that you can’t get into an ivy league with such complications and I agreed until my senior friend got admitted to Harvard with free tuition because his parent’s overall income was less than 65k.

For a little background, we’re both based in Texas and I’m just not sure if he got a higher gpa than what he’s been saying but he did get admitted.
