No sorry , actually its 100% the other way round. That claim seems legit and serious only to Rihanna stans , so dont go around telling people cause they will simply rub some Grammy receipts on your face.
Honestly...it's laughable.
Yeah... since Grammies defines what a good music is
Those are all dance songs.
Rihanna did Caribbean/tropical music with her first album, mixed R&B, pop, and ballads with her second album, did pop, hip-hop, dance, and R&B with GGGB, did hip-hop and pop with RR, mixed R&B, hip-hop, dance, tropical, and pop music with LOUD, and Talk That Talk was also hip-hop/dance.
Bloody Mary isn't a dance song...
Might want to do your research first
Rihanna has three truly great albums in my opinion (GGGB, RR, Loud) and three good ones (the other three.)
Gaga has on great album (TFM) and two good ones (the other two.)
So while Gaga could catch up with her next few albums, Rihanna has her beat right now in terms of consistency.
