It's likely correct that mass transit is directly subsidized at a greater percentage than any specific aspect of private car ownership. However, there are significant indirect subsidies due to the centrality of private cars that not only dwarf transit subsidies, but simultaneously make transit less economical.
A simple example is minimum requirements for parking. Almost every home and business is paying more for additional space that cars take up. This means less people in catchment areas for different types of transit.

Sure but that's not a subsidy being borne by tax payers, that's being paid by people that want cars to be at their house or business. I suppose you have some argument that the legally required minimums might be more than necessary but generally they reflect the need as it exists, not what we want it to bed. Allowing businesses to not have to supply parking wouldn't force people to use mass transit, it'd just force them to park further away in a space not paid for by the business they are frequenting.

When the cost is being borne by every single tax payer, then it's functionally equivalent.
Cars are easily one of the most subsidies goods in America. It's absolutely absurd how many trillions of dollars we dump into making automobiles work, even if they make no sense.
No - it is a subsidy to make life more convenient than either the purchaser or shop is willing to pay for. If the shop needs people to arrive in cars, then it’s worth it to them to put in parking.
And parking minimums are constantly criticized for being higher than necessary. How could they possibly not be higher than necessary in a significant percentage of use cases, when they don’t allow anyone to say “we don’t serve people who arrive at my locavore socialist workers co-op by car so we don’t need parking” - instead they get the same amount of parking as any other restaurant, which is too much.
