Nope. What the study actually says [0] is that it's equivalent in production of polycyclic aromatic hydrocarbons. PAH is a category of emission at which two-stroke oil-burning engines are disproportionately bad, and modern cars are reasonably good. If we measured on another axis (say, rubber particles), we could write a headline that cars are 1000 times worse polluters than leaf blowers. Like, leaf blowers aren't great for the environment, and maybe mandating catalytic converters for them would improve air quality, but these specific claims are all made in bad intellectual faith.
