Is applying for Trinity worth it?

if a person applies to Trinity, do they have a chance of being pooled to another college?

Hello, I have been looking into applying for Cambridge to do maths for a good amount of time now, I was thinking about Trinity but I have noticed a pretty sizeable number of posts on this website that talk about how much they did and all their grades (Just in general, *very* impressive candidates, even by Cambridge standards), but did not get an offer, and in some cases some were not invited to interview whilst clearly being outstanding students. I was wondering, then, if it was better to apply to another college to get a better chance of getting in. I was thinking Trinity Hall or Gonville & Caius, as I have gone to T. Hall a few times and like the campus, and G&C because they run a lot of support programs for my county, and so it might be worth applying to them. Of course, Cambridge will still be selective in the same ways, but from what I have seen, Trinity seems to be a big risk on my chances of getting in. I was wondering if this was true, and if I would benefit from applying to any other colleges? Because honestly I am not super fussed about where I go, I am only worried about getting in, so it would be nice to go to Trinity, but if it is a risk, I should weigh my options carefully.
