i think the chances of someone taking the effort to crack your password is lower than whatever bot they use to crack it
unless you are some kind of CEO or something, someone is unlikely to spend any time trying to figure out your password specifically (and frankly if you are targeting a single person there are far more effective and faster methods than brute forcing)
more likely, one of your passwords will at some point be involved in a hack of some website, and they will just be brute forcing it along with all of the others. then they'll have your password and your username, and depending on the site, possibly a few other websites where you happen to have an account. and of course they'd try the usual bank websites. if your passwords are all randomized, you're pretty much good to go. not only are all your other accounts uncompromised, but picking a new password to use on the victim site is trivial
