Does background matter?

So, in my case, I arrived from Egypt right before my junior year starts. Yet somehow I managed to get excellent ACT and will take SAT subject tests. I have a very good grades in both Egypt and USA. I managed to do some Extracurriculars as well.
let’s say for example there is another applicant who has the same test scores/GPA and similar ECs and we both have good essays.
Does that give me an advantage over him/her ? and I am asking from the point of background and credentials not from the point of race or ethnicity.
(It’s a simple question, so please please take it easy lol)
