Is this a correct view of MM hedging?

Apologies in advance if this is a poorly framed question. I’m asking because I’m genuinely trying to improve my understanding of how this actually works.

I saw a post from a Japanese investor arguing that, for a name like NVDA, option market makers’ hedging activity matters more for price action than spot supply and demand, and that last week’s close above 200 may signal that MMs are starting to unwind downside hedges.

Is this actually a correct understanding of how the options market works?

I get that MM hedging can influence short-term moves, but this explanation feels a bit too strong to me.

Would appreciate it if someone knowledgeable could explain what parts are valid and what parts are being overstated.
