Hey there @Gaddsch
You shouldn't let yourself getting discouraged because a course looks to complex for you at first watch or because you see the tutor using a lot of high end plugins. There's a learning curve for any one, with some frustration along the way, it just take some time to grab the all picture, nothing wrong with this, don't worry.
It starts with your DAW and what's included in the box, learn your native plugins & tools that comes with it, next to that there's a tone of free plugins that are really good and can be an alternative to 3rd party high end & expansive ones.
When watching "How to make" tutorials on S.A, try to grab the full picture as well as what techniques & effects were used to achieve the sound & the production. Identify & take notes of terms or techniques that aren't familiar to you and learn about them later. It's not about being able to replicate the exact same sound. For example, while you could copy/paste the exact same values shown on a screen inside the most expansive or best compressor plugin ever, it doesn't mean that you'll get a better understanding about how this compressor works or how to use compression in general. So things like EQ & Compression, effects, mixing & arrangement have to be seen like different pieces of the puzzle that you will learn with time. Again, Music Production can get quite frustrating, especially at the beginning but if you keep learning at your own pace & manage to keep the fun while doing it, then the journey will be much more pleasant. Many established producers will laugh or feel ashamed when listening to their first tracks, so don't blame yourself or get discouraged when your not happy with the results you have, there's nothing wrong with that, it's part of the process.
If FL studio is your DAW of choice, here's the page where to find FL related courses on Sonic Academy. On the left side of the tutorial page you can also browse courses by "Genre" or "Course Type" and on the right top page you have the "Magnifier" button to search courses with key words. Better than spending money on gears & plugins right now, give a try to a subscription perhaps, if you're seriously willing to learn about Music Production, there's a ton of resources on S.A website and again, don't get discouraged, just give it some time & put love & work into it, if you really love it, no worries, it will be rewarding at some point.
Hope that helps, here's the link for FL studio courses
