It very much depends on how close to hardware they are.

If someone is working with C# or JavaScript, they are about as knowledgeable with hardware as someone working in Excel(I know this statement is tantamount to treason but as far as hardware is concerned it’s true

But if you are working with C or rust or god forbid drivers. You probably know more than the average IT professional you might even have helped correct hardware issues.

Long story short it depends.
