You are correct, but your reading is still untenable.
So what you are saying is that you don’t understand the Ramba”m.
“Their minds are not lend themselves to education” is how I’m understanding you’re reading.
If you want to be very m’dayek, he doesn’t say “education”, he says “to be educated”. Your entire kasha then falls off.
If you don’t want to be so m’dayek, you can say that the Ramba”m is referring to a certain skill set required for Gemara, not necessarily specifically what we refer to as logical thought.
