For me problem is that people don’t understand that there are different levels of expertise.
Like if you can write an SQL query, you know difference between DDL, DQL, DML you are already an expert compared to average people.
Of course knowing that doesn’t make one database expert as you might not know how indexes work under the hood and might not know how to maintain a database.
Picking and mixing right levels of expertise is also hard because you never know what’s the next job will be.
