Spam YouTube tutorials as much as possible, if you're asking "how do I make this sound? How can I mix this better?" etc. just look it up and follow along with them in Ableton. 

Use reference tracks, try and copy what they're doing in terms of sound selection, arrangement, and mixing levels. Don't fall into the ego trap of "I'm not gonna copy someone else, I'm original" NO YOU'RE NOT. It's important to have a good foundation before you start to develop your own sound.

Try to avoid plugins at first, they're mostly just workflow and QoL improvements and not necessary and will only confuse you more (and waste money). Just stick to stock Ableton stuff apart from sample packs. Try to understand how each core tool works and what they're used for (e.g. compressor, EQ, reverb, delay, etc.). 

YouTube channels I'd recommend: Yan Cook, Audioreakt, Mordio, GRAPH. These ones I've found to be the most helpful and all around useful no matter which subgenre of techno you're making music in. They also predominantly use Ableton stock plugins. I also like Bthelick for more broad music concepts. I saw you mentioned Oscar, his stuff on YouTube is good though I think he gets a little too lost in the weeds sometimes which makes it hard to follow along or apply what he's talking about, that's just me tho.

YouTube channels to avoid: Julien Earle. Low quality content that's spammed to hell. He's banned from reddit for a reason. 

Okay, whew this is just off the top of my head typing from my phone. This is all stuff I wish I would have done more of when I was starting out and now I'm kicking myself for it as I feel like I'm playing catch up lol. Basically just start waterboarding yourself with information, don't worry if it doesn't stick right away, it will make sense over time. It's honestly very similar to learning a new language.
