How stupid am i?

1. I tried to learn programming language.
- It just so freaking hard for me to understand. Failed at logic.

2. Tried to learn aws.
- Technically know how it works but often forgot the services name. (Was thinking to get aws cert).

3. Tried to learn OpenSource DB.
- Can do up to db setup only. Else i didnt understand sh*t.

4. Tried to learn cybersecurity.
- Ended up bunch of unwanted process in my vm.

I was envy that some of my friend only read documentation once & he is like know what to do.

Guys, any pro tips for poor man here?
I want to code, but somehow i stuck.

I feel dumb...
