Was ist der Unterschied zwischen "Ausbildung", "Praktikum", "Fortbildung", und "Weiterbildung”?

I get confused between these all the times, so can someone give me a very simplified explanation here, so that way I can differentiate between them.

Was ist der Unterschied zwischen "Ausbildung", "Praktikum", "Fortbildung", und "Weiterbildung”?

"Ausbildung" can refer to everything education- and/or (job-)training-related after school, but most often refers to a specific type of education/training that could be translated to something similar to "apprenticeship". This more specific version is used for most jobs that require specific knowledge, but not on university level. Most such apprenticeships take around 2-3 years to finish, and you get paid while doing it (albeit less compared to after you finished).
"Praktikum" is colloquially refers to "internship". Sometimes - and confusingly - practical exercises in university might also be called "Praktikum". Since a few years ago, there should be not (legal) unpaid internships in Germany anymore. A lot of them are set at Mindestlohn, though (minimum wage). Most internships range from a few weeks to a few months.
"Weiterbildung" refers to additional training and/or education you receive on the side during your job and/or after your formal training has ended. It's a catch-all term which doesn't specify length or who is paying for it. It also doesn't have to do anything with the training you already got - even if it's a completely different field. It also doesn't have to be formal in nature - it might refer to you reading some books on the topic as well.
"Fortbildung" refers to a specific type of "Weiterbildung" which usually is formal in nature and expands on skills you are already using for work, usually taking a few days to weeks.

DANKE SEHR! Okay, so besides these I listed again down below, are there any other "Bildungs" or things like it that I should be aware of. Prepping for the Goethe B2 Exam btw

1. "Die Ausbildung"

2. "Das Praktikum"

3. "Die Fortbildung"

4. "Die Weiterbildung"

5. Usw.?

None that I can think of right now. I mean, the German education system is rather complex, so there are a lot of specific words for specific things in there. But among those, only a few are as general as those you listed.

I've also encountered "Lehre"; is this also a catch-all term?

[slow mirage]

Yes, it is. It may refer to any of three separate things: Either the more specific type of "Ausbildung" I've mentioned before. As a catch-all term for the teaching work that teachers and university professors do (mostly used when talking about meta-level stuff, like in politics). And lastly, it might refer to the teachings of a field of study.
So "Ich fange im Sommer eine Lehre an." would be something like "I'll begin my apprenticeship in summer."
"Ein Ziel der Lehre an Schulen ist das Fördern kritischen Denkens." would be "One goal of education in schools is the development of critical thinking."
And "Psychologie ist die Lehre des menschlichen Geistes." would be "Psychology is the field of the study of the human mind."

Thank you very much for taking the time to write thorough explanations!
