People do form weird perceptions, especially from short trips to places they don't know well, but your numbers are wrong.
137/152 are the number of days w/ precipitation, not sunny days. ie, Seattle has less rain, but more days of precipitation. This is typical comparing Seattle with many other cities: less rain total, but spread over more days.
Those more days are concentrated in winter, more so than in is typical in other parts of the country. If you look at the "hours of sunshine" stat over a whole year in your links, the typical seasonal change people complain about in the PNW is right there: Apr - Sep are similar, but Nov - Feb Seattle gets half as much hours of sun.
The concentration of gloomy drizzly days in winter is quite real.
