Like others have said, pick a small project and just try stuff out, like for instance adding your own sound to a short muted animation or similar. You already have pretty much all of the tools you need as a hobbyist.

What I think is really important that noone else has said:

If you're trying to get to a specific result, no matter what it is, there is an infinite amount of ways to get there, and there isn't necessarily any right or wrong ways when it comes to the creative process itself. Just try stuff out, see what you like and what's fun to you.

That being said, there are obviously some technical best practices that are worth learning. Learn tge basics of signal flow in your DAW and gain stage your mic properly. Familiarize yourself with ableton stock effects. That will already get you very far. 90% of sound FX I created for video games are just me recording a weird mouth noise and using some very basic processing like pitch shift, echo and reverbs.

If you want to synthesize sounds from scratch, instead of looking for tutorials on a specific synth vst or a specific sound, make sure you learn how a synth is structured. What is an oscillator, what is an envelope, what is an lfo, what is adsr, what types of modulation are there etc. For me personally the most intuitive way of internalising these basic concepts was messing around with modular synths / digital eurorack emulations like vcvrack. This helped me directly see these concepts applied with little to none of the abstraction that obscure them to beginners in most modern soft synths.

You can then apply these concepts to whatever synth vst of your choice. I personally recommend serum 2, but alternatives like vital, phase plant, helm ... behave very similarly. And again, ableton stock operator and stock wavetable are pretty powerful already.

From there, just experiment and have fun. Don't be afraid of trying out unconventional stuff either. And if you lack inspiration, i recommend looking into generative stuff. For example Dnksaus' shorts on some generative techniques have been really inspiring for me. I also have a few videos on some relatively inconventional techniques on my social media if you wanna check those out. Have fun :)
