The silicon lottery is mainly applied to cpu unlocked and alludes to its possibility of overclock. Intel's blocked CPUs like yours could (if they were unlocked) run much faster than Intel's block allows, so you have to take for granted the stock speeds.
Check:
Turbo boost and hyperthreading are enabled.
Open the task manager and make sure there are no background processes that interfere with the test.
Note:
Do not be overwhelmed with benchmarks, they are not important. What matters is your experience with the PC in real life.
Do not trust everything that is published on the internet about benchmarks achieved.
