Nothing wrong in trying out free software to get to grips with computer design.
The Adobe software, like a lot of the paid for software is very sophisticated - I’ll grant you that, but try
Gimp II, Inkscape and FireAlpaca first - all free.
I recently started using Affinity. It’s pretty good, but I don’t really have enough experience with competing apps (i.e. Clip Studio) to say whether it’s better or not.
One thing I do recommend is to NOT buy CorelDraw suite. It used to be a cheaper alternative to Photoshop back in the old days, but now it’s just overly expensive for very basic functionality that feels like it’s stuck in 2003.
CorelDraw. I remember getting a free version of that as a cover disk on a PC mag back in the 90s. I used it for years. No need to uodate, rebuy, rent. Just loaded it onto my desk top and used it. I was using it so long I had no idea how much things had moved on, It’s a bit like having a washing machine from the 50s that never broke - so you never replaced it and having no idea what modern machines were doing.
You can try Krita or another one called Gimp. I do some of my digital drawings and art in Gimp, which is similar to photoshop. But Krita is really good too.
