You need to put some glasses on. PSU is as good or better than half that programs on that list.
We are in the 2020's, not the 1980's so remember that. The list looks at a lot of different factors.
Texas A&M - yes, Penn State is better
Michigan - no, Michigan is better (national championship in 1997, national prominence)
Florida - no, Florida is better (3 national championships in 1996 and 2000's)
Notre Dame - no, Notre Dame is better (national prominence)
Oklahoma - no, Oklahoma is better (1 national championship, college playoff, and consistent Top 10)
Clemson - no, Clemson is better (2 national championships, college playoff)
USC - no, USC is better (national championships, beat PSU in Rose Bowl, national prominence)
LSU - no, LSU is better (3 national championships in 2000's)
Texas - no, Texas is better (2005 national championship, national prominence)
Georgia - no, Georgia is better (national prominence)
Ohio State - no, Ohio State is better
Alabama - no, Alabama is better
Penn State is better than half the programs above? Which ones and why? Take off your Penn State blue colored glasses and GOOOOO.....
By the way, the Wall Street Journal valued the Penn State Football program as the #13 highest valued football program in 2019. All of the programs above, except for Clemson and USC, were valued higher than Penn State.
