I guess, to break it down, THIS is the part that baffles me.

Previously, undocumented immigrants were not qualified to receive comprehensive health insurance but were allowed to receive emergency and pregnancy-related services under Medi-Cal as long as they met eligibility requirements, including income limits and California residency in 2014. In 2015, undocumented children were able to join Medi-Cal under a bill signed by then-Gov. Jerry Brown. In 2019, Gov. Gavin Newsom signed into law an expansion of full-scope Medi-Cal access for young adults ages 19 through 25, regardless of citizenship or immigration status. Access was then further expanded to allow older adults aged 50 and older to receive full benefits, also regardless of immigration status. The final expansion going into effect Jan. 1 will make approximately 700,000 undocumented residents between ages 26 and 49 eligible for full coverage.

What part of the word "undocumented" does not really mean "illegal"? I looked it up and tried to figure it out. Here's the explanation of the difference between using the term "illegal" instead of "undocumented" that I was able to find on some site full of legal mumbo-jumbo.

Regarding using the word "illegal":

"It is legally misleading because it connotes criminality, while presence in the U.S. without proper documents is a civil offense, not a criminal one."

Ok. I think I understand now .... ? So, does that mean it's kind'a like the difference between a misdemeanor and a felony??? So, going by this assumption, I'm guessing the misdemeanors like assault and battery, shoplifting, DUI, vandalism, perjury, burglary, gun possession violations, etc. etc. etc. aren't really ILLEGAL actions, so we should just ignore them. Or am I still confused?
