Have is used with the pronouns I, you, we, they, and also with the names of people or things, if they are plural. Here are some examples to make it clearer:
I have a passion for video games.
You have an amazing talent for drawing.
They have three different projects to finish by Friday.
My friends have an exciting plan for the weekend.
As you can see, have is used when talking about yourself, you, or many people at once.
