Basically the biggest difference between the legal rules and legal principles is actually stated in line 38.
Hart is saying that hey... legal rules are explicit rules. So in a certain situations, they either can be completely applied or not at all; there is no partial application. Thus, judges need to use their discretion to rule in a certain cases where the legal rules can't be applied.
Dworkin says hellz no. He says that legal rules, not only they contain "rules," but also principles: these principles are underlying rationale behind the legal rules. Thus, judges don't have to use discretion but those principles to make a decision.
In regards to your question, open texture is what creates the "legal indeterminacy." What happens is that legal rules contain general terms that can create controversies depending on how one interprets: For example, like in the passage, one says "no vehicle in the park." Well when I think about it vehicles mean "cars" but when someone thinks of a vehicle, it could mean a "bicycle." well... which one is it? Does this rule allow bicycle in the park or not?
