A Eurorack module (or any other format module) is generally just one piece of system that's necessary to make a Eurorack rig work. It's like buying a propeller, a seat, and a rudder and expecting to have a flyable airplane.
By the looks of it, you're buying "cool" modules but you don't understand the architecture that allows them to work together to get a creative result.
Understanding how a DAW works or being able to tweak the controls of a VST synth won't get you very far. That's a bit like walking into someone else's already patched rack and twiddling with the knobs. You can be an awesome race car driver but not understand how to build or rebuild the engine that makes it go.
Spend some time with software like VCV Rack and start building and patching. Until you're proficient with that aspect as well as identifying and using the utility modules necessary in just about every rack, you'll be pretty hard pressed to get the results you're hoping for.
