Do homeschooled students actually get into Harvard?

I know Harvard says on their website that they treat every application the same, even for homeschooled students. But I’m wondering if they actually accept homeschooled students for undergrad, and whether their chances are lower compared to applicants who attend a regular high school.

Also curious if this is the same for other Ivy League schools.

For context, I took IGCSE and I’m currently doing AS and A Levels, 1400 on SAT
