The vulnerability of every account doesn't depend on the people behind them - it depends on the site itself...IF IT'S NOT SAFE, THEN ITS NOT WORTH DOING AT ALL!
No the users get hacked due to their own less-technical nature and the site has nothing to do with that. I have seen many hacked Gmail, Netflix, Hulu, Amazon, ChatGPT, and so other platforms accounts getting hacked and those sites are considered as secure by the users.
If the database of the site gets hacked then that's a weakness in the security of the site but if a user's account gets hacked then that's not a weakness of the site but of the user who doesn't took care of his/her account and used a weak password or somehow his/her system got compromised.
