No they aren't, they're data. Your source shows the amount of Linux CVEs in 2024 are an order of magnitude higher than the amount of Linux CVEs in 2023. Does that mean Linux became way more insecure in 2024? You imply it does, but that's obviously not true. What happened is that Linux changed how they report CVEs [0].

Just like your source doesn't say anything useful about the difference in CVEs in Linux, it doesn't say anything about the difference in CVEs between Linux and OpenBSD.

Lies, damn lies and statistics.
