The wheels are factory, I think?
Regardless, the marking on them is the clearcoat lifting and the white is corrosion forming underneath.
The corrosion is cosmetic, rather than structural.
The clearcoat lifts due to a combination of age, UV exposure, mishandling and harsh cleaning agents.

Zoom viewings are useless for detail stuff. Their only value is to hear the noises the car makes when it is running and being driven.
For cars being sold by humans, ask (in writing) for clear photos of the problem areas - let them know that you understand a used car won’t be absolutely perfect, but you want a proper understanding of its inevitable faults - if they can’t get their head around this, then they are not the right person to buy a car from sight unseen.
This also provides a degree of legal recourse if they omit things.

Considering the couple of clear “mistruths”, I would seriously investigate the possibility of getting a full refund. Laws and circumstances are highly variable, so I am loathe to suggest that you have a strong/weak/otherwise case, but if you don’t think that you can love the car, then it would be worth researching.

All of that said, the car looks like it can be brought back to close to your expectations.
A professional detail will sort most of the cosmetic issues, and will reduce the interior smell. After a proper clean, the smoke smell will continue to diminish over time, especially if you leave the ashtrays half-full of bicarb soda.
The wheels can be professionally refurbished, but I would have to weigh up the cost of this against the irritation they cause in their current state.
