It's a really bad idea to think that an address is your bank account, because an address should only be used to receive coins once, and you should give a new address the next time. So, it's closer to something like a one-time payment request. Unfortunately, people, especially beginners, ignore this and indeed use them as "bank accounts". This destroys their privacy and it becomes extremely easy to track all their Bitcoin transactions.
There are 2 bitcoin block explorers have features to analyse and give results on privacy levels:
https://blockstream.info and
https://blockchair.com/bitcoin.
You can try to type your own addresses or txid to see how good your transactions are and try to figure it out what you can improve on your future transactions.
Blockstream.info does not have privacy score but blockchair.com does have privacy score levels, from 0 to 100 and they classify it into 3 groups: 0–59; 60–89; and 90–100

Privacy-o-meter of Blockchair.comI keep something in my mind for practice:
- Don't bookmark my bitcoin address on browsers.
- Don't search my bitcoin addresses with browser without Tor.
- Don't store my bitcoin address or txid on any messenger apps.
