Are a yacht and a sailboat the same?

No, a yacht and a sailboat are not necessarily the same. The sailboat is, as its name implies, a watercraft that moves under wind power. The yacht, on the other hand, could be a sailboat, but it does not have to be. The yacht is a larger vessel (usually over 30 feet in length) used for recreation, and the yacht can be (and usually is) classified as either a sailing vessel or a motor craft.
