They are very similar, but there are small differences between them.

Gameplay Mechanics are the mechanics within the game that affect gameplay. Stuff like stats, weapon modification and augmentation, and parameter bonuses are mechanics.

Gameplay is the actual gameplay, what you do to play the game. Rolling, healing, gestures and bonfires are examples of gameplay.

There are circumstances where it could be both. Parry and riposte, and backstab, are gameplay because you can do them in the game, but they are also mechanics in that they put multipliers on the damage that is done to enemies.

I hope that made sense.
