2 year old speech

Can anyone give me some advice on how to help my toddler? She says tons of words, can count to 10 on her own, and knows about 75% of the alphabet.

I’m struggling with her understanding questions. Like if I ask her “are you hungry?” She won’t say “yes or no” she says “hungry” and runs to her chair. Or if I say “do you want your hair up?” And show her the pony tail she will just look at me like I’m crazy. Like I’m just afraid she’s not comprehending things? I do try and say “yes or no” and shake/ nod my head. Idk, she turned 2 end of November so maybe I am just being paranoid. I just see all these “social media” babies talking and using full sentences at 2 years old and I feel like I’m failing.
