Incorrect.

First, let's be clear, "our understanding of the laws of physics" is not "the actual laws of physics". Every physicist knows this. The universe always follows the real laws, physicists are very excited about the difference because it's a chance to win a Nobel Prize.

For example, the one in 1980 for the discovery (in 1964, they're slow to award the prize) of CP violation in decays of neutral kaons, which is fancy physics language for "matter and antimatter do not behave the same way". This year, the LHCb experiment in CERN also discovered CP violation in baryons.

In fact, this is in your own linked article from CERN: """In the past few decades, particle-physics experiments have shown that the laws of nature do not apply equally to matter and antimatter. Physicists are keen to discover the reasons why."""

That said, personally I like the response from Sabine Hossenfelder: There's nothing to be explained, conservation laws only apply to time-evolution of a system, not to the initial conditions.

We don't look for a reason why the mass-energy was non-zero, why do we even need one for why the baryon number isn't zero?
