If anyone has the time & ability to give me some insight/perspective/advice, I would truly so appreciate it!!!

Here is my situation: I graduated in May, planned to take one gap year, took the LSAT in September, and am now recognizing that I need far more time to study for the LSAT if I want to have a legitimate shot at my goal schools. I would like to attend a T14, so I am determined to score in the 170s. I was BRing around this score (but..my score would fluctuate quite a bit). Thus, I was not too surprised when I scored a 163 on the September test.

Basically, I am certain that if I took more time, I could score much higher, which would give me a good shot at the schools I am hoping to get into. So (partly since I am 21 and am personally in no urgent rush to start law school as soon as possible) I want to just take the time to study more for the LSAT and wait another year to apply to schools. However, my parents are very against this, and they think that November should be my last shot, and whatever score I get..that's the score I get. They honestly do not have many reasons for this, aside from just wanting me to get started with law school and not take any more time than necessary. I do not think they fully grasp the significance of everything from the LSAT score to the ranking of the law school one attends, but they are also not particularly amenable to me trying to explain it to them (they are both attorneys themselves, but honestly I do not think their experience was the same as it is today).

Has anyone has walked a road similar to this one before? Or anyone have any insight on how I should go about this? I am keenly aware that this is a highly personal situation that is very specific to my life, but I also believe that many law school applicants have had to have gone through this before, and I would really love to hear some perspectives on the matter. Do you have any advice on how I should go about this with my parents? Thanks in advance to anyone who can help!!
