Oh nein, nein, of course. Transmutation is the art of bending, changing, molding one item into something else. It can be as simple as turning a plank of wood into a cup of gold with some magic. But it can be as elaborate as changing one's body into another form - I am able to change myself or friends into a number of creatures for a period of time.
Evocation is control over elemental magic. I personally have an affinity with fire spells but it also includes a pool of spells involving frost, thunder, lightning, acid, water, earth, etc.
