Yes, the gameplay is the same
Ocarina, Majora's Mask, Twilight Princess, and Wind Waker, have the same damn gameplay. Legend of, Link to the Past, Minish Cap, Four Swords Adventures, Awakening, and Oracle of X have the same damn gameplay. Sure there are tweaks; the combat and exploration is identical depending on the dimensions that the game happens to utilize though, and all changes to gameplay have been for the better over time, except for that ******* clock in Majora, but a lot of people liked that so whatever.
Adventure of Link stands out as the only one not copied... except by the Zeldas that shall not be named. I guess Phantom Hourglass also stands out in terms of gameplay, even if the actions are the same as in other 2d zeldas, the control is quite unique. By and large, however, the Zeldas which share a spatial dimension control exactly the same.
I don't really know what else you could be talking about besides gameplay. If you're going to criticize a Zelda over something other than the gameplay then I'm not sure why you would even like Ocarina. It's "story" is beaten in other games, it's characters are beaten in other games, it's atmosphere is beaten in other games, it's graphics have been surpassed (in both style and technical detail,) and so on.
