If you watch most people typing they occasionally glance at the keyboard, especially for little-user keys. A true touch typist should be able to type for extended periods without looking at the keyboard at all even for only occasionally used keys. Also true touch typing minimises finger and hand movements by using as many of the fingers of the hand to type with as possible, while most keyboard users rely on a few, and often just two fingers for most or all typing.
