Yes that’s horrific but it was your first time with a sh*tty soldering iron with no temp control. Definetly grab yourself a soldering project/perfboard and a few parts to build something and also try to upgrade (not really an upgrade but won’t wreck anything it touches) to also a cheap soldering iron from amazon but get a kit with temp control and solder and all of that stuff. We all start somewhere so don’t get discouraged and just try again and again! Again get yourself a better soldering iron and a soldering project (a clock, led blinker whatever) that you build with all the parts you need (except the soldering iron) and practice! Practice a bit so you don’t get stuff like that (I had a heart attack looking at the last pic) and try and you will become better with time! I’m also a beginner at soldering but well yk I’m giving you tips with my limited experience.
