Princeton is hard. It's hard for most people here, regardless of stats / preferential admission (I'm thinking athletes, legacies too), etc unless you're just a genius. Which most of us aren't. So if you don't want to work really, really hard and you think you might be academically disadvantaged at Princeton, take that into consideration. You know yourself best!
But if you get in here -- chances are that Princeton believes you can succeed. We have something like a 98% four-year graduation rate. (I made that up, but you get the idea.) This isn't Colgate, which was described in that (very interesting!) article. There are plenty of resources here for EVERYONE. There's a pre-frosh summer bootcamp for the less academically strong admits (often athletes! preferential admission is NOT just a race thing...), and a ton of people take advantage of the free 1:1 tutoring, study halls, etc held for most intro classes. I've seen preceptors do 1:1 tutoring session with struggling students. Help is available here.
I really don't think that there are many huge "mismatches" here, except probably for the kids of super-rich donors (if that? haven't met any myself). There are just so many awesome applicants. But I'm no expert.
So go ahead and apply, I'd say.
If you want to check out the typical level of a Princeton course, for the first time this fall Princeton is offering a few on Coursera, although they aren't really representative: https://www.*************/princeton
And good luck!
