On the left side of you should have a z limit switch, make sure all the cables are connected to it and adjust it so when you're in the lowest position the nozzle is just above the bed (put the bed in the lowest position too and leave a small gap between the nozzle and the bed). You can read more about it here: https://all3dp.com/2/ender-3-pro-z-offset/ Then you can try to level the bed using for example some youtube tutorials like this one: https://www.youtube.com/watch?v=YHP2DfRl-GQ

Hi, there are a couple ways of leveling the printer, it might be a bit difficult at first but will get easier over time. You can watch some tutorial videos on youtube how to do it like https://www.youtube.com/watch?v=YHP2DfRl-GQ and make some test prints to see if every corner is aligned correctly: https://www.youtube.com/watch?v=VOBkerYJJ8s

Check if all the wires are connected properly, had a similar issue when I got my first ender.

I think something went wrong with uploading the picture and we can't see it. Printing abs is much more difficult than printing pla, you can watch some basic youtube videos about printing abs like https://www.youtube.com/watch?v=ZvEsrF0sWdk for example. Please try to post the picture again so we can see what exactly might be wrong.
