Yes privacy is important for beginners because it's a matter of time the beginner today will become a teacher or learned person and if private details is leaked due to many government procedures like AML-anti-money laundering and kyc procedures of crypto exchanges procedures being asked of users when wrongly stored , may affect the user in question so privacy is very important for all.
This is really an issue because these procedures do not in anyway protect our privacy as someone somewhere get these information and may use it against us and I'd mention few precautions we can take although some are already being fought by government to stop them like already done to Lavabit , the CEO rather shut down the website than give government details of her users but not many will do this now... examples of measures we can take to protect our privacy is
*Every beginner or user should be vast about government laws regarding privacy so that when we're being asked what we're not supposed to give out we'd know and not give out such details

* Use of VPNs is also another means of ensuring privacy although not many countries are in favour of this

*Use of 2-FA mode to ensure our details are not used on our behalf

There are many more and I'm sure we'd learn a lot from this thread. I hope this helps
