As a general statement: If it states Non-Stick, Non-Stick Surface or like terms it will be Teflon or a Teflon 'like' coating. Or, it states that the surface does not need the user to apply a coating, it likely to be Teflon or a Teflon 'like' coating.
In the past, Griddles had been made of Cast Iron and required a 'cooking oil' build-up coating prior to cooking, i.e. it took a couple of weeks to develop a good cooking surface. They required a little knowledge on how to cook with and clean them. The advent of the 'Dish Washer' pretty much killed the time developed cooking surface of the Cast Iron pot, pan or griddle. Rendering that surface back to a near 'like new state'. Which, resulted in things sticking and burning and worst of all, a very mad Grandmother! Well to many of you, a very mad Great Grandmother.
One needs to be very careful regarding Ceramic Coated products. A true ceramic coated product will have a Cast Iron base with the Ceramic Coating, and it will be notably heavy! In addition, it will be a more expensive product. So, if you come across a light weight, inexpensive 'ceramic coated' whatever. Leave it on the store shelf!
If you buy a true Ceramic Coated cooking product. Read the directions carefully and follow them! They can be damaged by many of today's very strong cleaning products. And, it would be better not to place them in the Dish Washer,
