For the most part that is true. Games like Titanfall also anthropomophize their mechs more than mech warriors will. Yes in MW the mechs are often humanoid in shape but it is still a machine. It's a glorified suit of power armour that is slow, stompy and more of a battlefield asset like a tank would be. Or an artillery piece.

 Titanfall is more like a human piloting a larger human that happens to be made of metal. Those mechs are even capable of finer dexterity, even acrobatics to a degree. 

They are very much a different interpretation of the 'mech' and you don't tend to see both variations mixed often because they don't tend to mix smoothly. Also because it doesn't make sense to have both styles in place because they are all different. Any setting you look at picks one or the other. Big and stompy or borderline human in its abilities.
