One year difference is huge when in that age range.
I went to school when I was 6,5 years old. Everybody else in class was 7 with some months. I was the weakest and could not do anything properly despite the fact that I'm pretty gifted. I could only get good grades for any subjects in the fifth grade. And even now I feel the weakest and the least protected by default. ADHD certainly didn't help too.
So no, being 7 years old and being 7 and 3/4 years does give you a big advantage. The fact that everybody is uniform only magnifies it.
In the workplace everybody have the different age, story and skill set, so this hardly applies. It's no longer a function of two variables monotonous on both of them, but a function on dozen.
And also while small difference give clear boost in competitive environments, it's not so obvious in cooperative environment.
