I'm thinking about this from a compassionate communication perspective.
I think trying to figure out who is "right" isn't useful here. Instead, understand why she is waking you up, explain to her why you want to sleep in, and come up with a strategy together to meet both of your needs.
Let's focus on your mother, since she's usually your caregiver. You're in a situation where your mother has authority over you and you want to convince her to change the way she's behaving.
This is a situation where you and your mother have different needs. It sounds like you seek the freedom to make your own choices and the comfort of feeling like you've gotten a lot of sleep. Your mother, who is responsible for looking after you, might want to protect your health, give you practice with a "normal" sleeping schedule that you can maintain when you have work or school, and get more of a chance to see you while you're awake.
If you understand why your mother wants you to wake up earlier than you want to, you'll be better-equipped to suggest a strategy that suits both of your needs. Talk to her and find out why she's waking you up, and explain to her what your needs are (that you feel better with more sleep, like staying up late, and want to make your own choices). Once you both feel understood, you're in a place where you can discuss approaches.
Don't come into this conversation to try and convince her of a certain solution. You need to arrive at a decision together that meets both of your needs.
Remember: right now she's responsible for you: financially, ethically, and (in some places) legally. One reason why parents deny their children freedom and agency is that if their children mess up then any consequences are the parents' fault... and usually, parents feel very bad if their children are hurt or otherwise suffer bad consequences. So even if it seems like your sleep is none of her business, she may care about it more than you might assume at first.
