the sprite, is like a "container" where you can store animation and frame (image).
now, the tilemap, is a "special" container where the picture is split in little tile (you chose the dimension of the tile) and every single tile take the picture from a one picture of the tilemap sprite.... if you make one it's easy to understand, english is not my first lenguage... and with this, you can set the tile in the tilemap (on the tilemap bar)
why tilemap is good?
because with one image, you can make an infinite level/map... and also very important, you can store all of the data of the tilemap in one ARRAY.
and off course, for design the level is very simple... when you have your tileset, you can make all of the level of your game.... 1 sprite, for the level... this is important for the performance to...
