Will i realistically be able to save?

Hii, i dont usually post on reddit so sorry if this is badly worded.

Im 18 years old and 2 months into my first job, its only a 16 hour contract and I’m earning around £800 a month (weekly pay £200).

I live with my dad and he has just calculated what i owe him for the house every month (rent,bills and council tax included) he said £332 a month (or around £83 a week). He split the full cost of the house equally by 3 (Dad, Me, Brother).

He and my brother earn significantly more than me monthly (granted they work more hours but im only in a retail job i cant rlly boost my hours at the moment). Is this a fair price for me?

I will still need to pay for my own necessities such as food. And ive also expressed interest in starting driving lessons which arent cheap.

2 years ago when my brother worked in retail and was earning similar to me he didn’t have to pay anything since he was saving for a car and taking driving lessons.

Since its my first job im not that good with money right now (i dont know whats good pricing or bad pricing for rent stuff) i was wondering is it still possible to save money while not avoiding going out with friends as much?

Any tips?

(Also is it a fair price to pay monthly?? Im not sure if I’m being over dramatic lol)
