Lots of different things here but the answer is yes, no, and maybe. There is no way to know at this point in the game and it comes down to who you are competing for nominations and which slates you are both on. You here all these comments about three from my district, two from my school, etc but what is not being said is their appointment source. This year my our district has at least two appointees and neither are from our local MOC. Here are the scenarios:
1. Recruit is a Blue Chip athlete. Each coach has a few of these "chips" that they can use for an outstanding athlete. These are basically Academy nominations and appointments. If the athlete truly has one of these, it will not affect your chance of appointment. The athlete may not even apply for other nominations as he is already in. Please note that there are only a few of these each year.
2. Recruit shows potential and his file is identified as a recruited athlete. They will compete for the same nominations and appointment slots as you. They will get a few more points in the WCS for athletics but they would have to be the most qualified candidate to win the slot.
3. Recruit competes and does not win his slate. After the first 150 individuals are taken from the NWL, the next group are called additional appointees. The academy can pick and chose here and give additional consideration to recruited athletes.
So that is the explanation of the process but to go along with what everyone else says, only focus on what you can control and do your best. If you are the highest ranked individual on your slate, you will get an appointment regardless of the recruit.
I would disagree slightly with the comment that you are competing against everyone else who has applied. While this is technically true, you are most likely to gain an appointment as a high school student by winning your slate. Appointments from the first 150 of the NWL are very difficult for high school students as the scoring system gives a significant advantage to re-applicants.
I would also agree with my friend @Cerberi
. Do not think you will get special consideration because you are a women. You have to work hard and do your best to be the best candidate that you can be.
