No advantage, only level difference

No type advantage here, but it wasn't too hard to take out that Pokemon.

"Haha, fooled you! I dunno 'bout tactics and stuff 'cause I didn't do my homework," Joey says before handing you $140.

Before you leave, he gives you a little tip. "Poisoning an opponent will slowly drain its HP. Paralyzing 'em can prevent its attacks. Some Pokemon moves come with all kinds of effects, so watch out." Anyways, you can either go for the next Trainer or go through the tall grass to catch some more Pokemon.
