If it is a removable bed, pop that bad boy in the freezer for a bit and the print should pop off. If not then you may want to try some glue stick on the bed before a print which will help the print release since it'll pull off the glue.
That's fair, there is a bit of information overload online when looking into it.
If you want my two cents, find the cheapest print with auto bed levelling (mingda magicians are good and cheap) and just start playing around.You don't need to know much to start, and you learn what you need to as you encounter problems.
That's how I got into at least, and now been printing for like 5+ years.
