I'd think it a pretty good bet that most or even almost all stars have planets.

Whether they have planets or not, it's a better bet that all stars have at minimum a disk. Since stars by definition form from collapsed dust fields, it would be some kind of physics to find a star with absolutely nothing orbiting it. Whether all stars have enough debris and enough time to form planets remains to be seen on a case-by-case basis.
