Some of them are, but hackers won't go on bruteforcing rampage for passwords anymore.
From my experience the main reasons behind hacked accounts are these:
1. Keyloggers - if you are worried about this possibility you may want to start using virtual keyboard, when typing password for important sites like your online BTC wallet or exchange.
2. Remote Administration Tool - can give hacker direct access o your computer.
3. Viruses/Trojans
4. Database of the service you were using got leaked, along with your login/password.
About your post I think you are mostly correct but we still need strong passwords to protect our accounts.
