Hi,
I don´t know if it is expected behaviour, but during my testing with an exposed Minecraft server through pangolin i found out that I can connect to my server with [literally_anything].example.com . Is this because I have set up a wildcard subdomain ( *.example.com ) in my cloudflare dns settings?

I followed the documentation and the youtube tutorials provided by Fossorial.
The http/https proxies work just as described. Also the Minecraft server (exposed TCP 25565) works great...well too great I gotta say haha.

Is there a way I´m missing so I could have only eg. minecraft.example.com that gets routed to tcp25565 without having something.example.com also be able to connect through tcp25565?

If you set wildcard subdomain then you will be able to use anything.
*.example.com CNAME example.com means any subdomain will always go to example.com. If you want only a single subdomain, then you should create a single CNAME record for this.
blabla.example.com CNAME example.com.
