There's no such thing as being too young. I've been fascinated by Rome since I was about your age, and figuring out where to start is a reasonable problem! The good news? There are a thousand different places. The bad news? There are a thousand different places.
To begin, you're going to want to scratch the surface with something fairly readable. I understand that you're quite eager to learn, but if you start by reading the Georgics, you're probably going to fall asleep. Sorry to anyone who likes them. They're dull. I'd recommend a couple of different modern authours for you to look at first, myself: Adrian Goldsworthy and Phillip Matyszak.
The former is one of my favourite introductions to the topic, because he writes for the intelligent non-specialist. Everything in his books is well-sourced, but he also doesn't assume that you're a) going to source check everything because no one does that, and b) he doesn't assume that you know things off the top of your head (like the intricacies of the Roman political system in 50 BC, because the Romans didn't know what the hell was going on then, either). While his biographies especially are focused on individuals, he also gives vital context into the world around them, which I found to be an excellent way to segue into new topics. He writes other books besides biographies, too - a wonderful book on the Punic Wars, Roman history through the eyes of the generals, etc - but I'd personally recommend you start with his Caesar, Antony and Cleopatra, and Augustus.
Matyszak usually can also be found writing in that same genre, and I'd recommend you read him second. He also gives context and wonderful explanations, but he also gets a kick out of writing books about things that don't have books yet. While I have a lot of fun with those - and with his writing style - it's also best starting with the broad strokes before you get into the (comparatively) smaller historical events. Some of my favourites are his biography of Sertorius and his book about the Roman conquest of Greece.
After you get a good start with those secondary sources, you're going to be interested in seeing where all of this came from, and we have more good news there. The world of Classics has happily embraced the power of the Internet, and thousands of primary sources are online in translation. While those translations are not always spectacularly good (I particularly disagree with their word choices as often as not), they're still a fantastic way to just start reading the content. Again, broad strokes before details. When you learn Latin and Greek, you can always go back over them. With those primary sources, I don't want to suggest much quite yet - after you've read a bit of the secondary (modern) stuff, feel free to message me and let me know what piques your interest!
As someone who started studying Ancient Rome recently I'd recommend (as a starting point) Mary Beard's SPQR. It's a stylistically-written breeze through its history from foundation myths to the Empire's fall - and covers in detail the key moments and motivations. I found it an excellent primer. While reading, I'd use Wikipedia to fill in the blanks, on specifics like military structure etc.
Anyhow, I'm new to this topic so do give the other recommendations a look. Being in your position, what seemed intractable became accessible and enjoyable in SPQR. Good luck!
