I don't know, but I'm sure it has. If your primary interface to MySQL is a GUI tool where you just click the "create table" button, type in a name and accept the other defaults, you could be using MyISAM tables without knowing anything about table types.
Don't forget, that 10 years of experience could just be 1 year repeated 10 times. A cardinal number of years doesn't always equate to increasing breadth of knowledge.
Of course it doesn't, but if 10 years of experience results in domain expertise somewhere else, but some cherry-picked detail about storage engines is missed then there is probably a good reason for it.
In my experience, someone with really strong domain expertise in something like bioinformatics, doesn't actually have 10 years building websites on MySQL.
