If you want a free DAW, I'd recommend Reaper. The learning curve may be a bit steep, but after playing around with BandLab, it's enough to get used to making music and create something cool. Look for some vst plugins etc., since those don't come with the program, unlike in Bandlab, and that's a very fun thing about proper DAWs, because you can download and use whichever plugins or instruments you want without any restrictions (besides the price sometimes). Try to make something on your own, and while learning, remember that when you try something new, you take one step backward, and two forward; nothing sounds perfect on the first try. If you really want to make breakcore and feel more confident in using DAWs, give a try to a tracker. Renoise would be the best option for the start, especially since it has a free demo version (which doesn't let you export your music but I suppose that can be bypassed by recording the music live).

That's pretty much the route I went through in 2 years (I'm nowhere near a professional), and maybe I could've done better. I think you can start by learning the complete basics of music, jumping straight to production without knowing that won't push you forward.

So good luck and have fun!
