If you repeat something often enough and use enough CAPITALS, it will eventually become true.

The section in question addresses the power of Congress to exercise exclusive jurisdiction over territory within a state purchased with the agreement of the state legislature.

Public, federally owned lands within a state are not under the exclusive jurisdiction of Congress. If I kill somebody on BLM or National Forest land, it’s a state crime, not a federal crime. AFAIK, anyway.

“If I kill somebody on BLM or National Forest land, it’s a state crime, not a federal crime. AFAIK, anyway.”

It’s both, and the Feds have jurisdiction.
