Did anyone ever say ALL stars have planets? But anyway, MOST stars probably DO have planets!
And no, 99.9% of planets confirmed by NASA are not orbiting high metallicity stars, that's nonsense. Stars with more than 1.5 times the metallicity of our Sun* host only around 16% of planets discovered and confirmed. At least according to NASA's Exoplanet Archive.
see - https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PS https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/np... - And then under the column headed Stellar Metallicity [dex] put in ">=0.176"
*The average metallicity of the stars in Kepler's Field of View was about the same as our Sun, very slightly lower 90%, so a small percentage of low metallicity stars to begin with.
