Yes and no. I’m still learning just as you, but...
You don’t have to add 「か」 to form a question. Tae Kim mentions this in another part of his guide somewhere. What matters the most is raising the intonation of your voice. In the example, that is more of a informal, casual way to write and/or speak. If you want to be formal and polite, then you would/could add 「ですか」. Take this example in English:
Someone points to a girl that looks older than her and says, ”That’s my younger sister.”
A person standing near by can simply say, ”Younger?” instead of ”That’s your younger sister?”
You’d know the person was making a question based on the sound of their voice. Hope that helped clear some of the confusion. Anyone feel free to explain better. :)
