As you already know, some creatures that aren’t ponies are the same size as ponies, while some creature kind are smaller. However, just imagine what would happen if a creature had the ability to grow, and become a giant, and then make themselves bigger than the ponies.
Example:
As shown above, Zecora (standing in the mountains in front of Ponyville) becomes a giant after obtaining the ability to grow, making her the biggest Zebra in Ponyville, hoping to rule Equestria at the size she’s at.
So, as you all know, ponies can’t always be the biggest creatures. Ponies are going to have let some other creatures get bigger these days. After all, Equestria has magic, and I believe that any creature could have the ability to grow into a giant and make themselves bigger than a pony.
