Yes, but it's so likely that your work is somehow wrong (in that it was misimplemented), that hueristics are employed to fail it early. If you can't easily point out why your work comes to a different conclusion than prior work, then it's likely you've failed to actually look into the prior work effectively.
And it's very unlikely you've managed to upend a body of work you didn't even know existed, and has probably run into several errors before (which you probably didn't avoid, because you didn't look into it).
If you did read through the previous literature, it shouldn't be difficult to specify and compare.
It's possible for you to come from no background and upend everything.. but the chances are simply (and largely) in favor of a mistake being made. The onus is really on you to double-check and triple check your radical conclusions
