Idk. I’ve been using my ender 3 v1 without an ABL probe of any kind just fine. The main problems occur when the shitty stock buildplate (the super thin buildtak one held on with binder clips) warps under high heat and you have to contend with high spots. Getting a probe could have solved the problem, but I just swapped over to a magnetic spring steel PEI buildplate, and after a bit of live leveling, I’ve printed things using the full buildplate once or twice so far with proper adhesion throughout. The only thing that I needed to do to use that was to stick a magnetic sticker on the stock aluminum bed. If OP needs a link, this is the kit I bought: www.amazon.com/…/B07XBM24HN

Would an ABL sensor be nice to have? Absolutely. But you can technically do without it if your buildplate isn’t warped and you are very good at live leveling.

Oh, I also have the stiffer yellow springs installed, which helps the bed stay more level than the stock springs. That probably helps as well.
