Close, but not exactly true. Rhynchocephalians (represented today only by tuataras) are also lepidosaurs but not lizards, while turtles are not lepidosaurs.

While it's legitimate to distinguish between lizards and snakes in a popular sense, it should also be pointed out that from a cladistic point of view snakes are just one kind of lizard. Snakes are more closely related to some kinds of lizards than those lizards are related to other lizards, making "lizard" a polyphyletic group in the taxonomic sense.
