Exactly. Lightning minimizes the use of the globally consistent ledger, which inevitably has to make trade-offs due to the "trilemma". You set aside some funds on the global ledger and then you can use those funds to transact in a much more efficient, truly p2p manner, without touching the global ledger. Eventually, you net out everything and settle it all at once on-chain, utilizing its features to resolve any conflicts.
