Madara's and Obito's knowledge came from the tablet. In the tablet, according to Obito, its described that Hagoromo became the God he are from the fact that he sealed the TT in his body (at the time Obito was questioned about the Chibaku Tensei, a Rinnegan technique or Yin-Yang technique, yet Obito attributed it to the TT). The same thing happened when both of them became the TT's Jinchuuriki. Madara said something like "So this is the Six Paths Power", while Obito claimed that he was the Second Sage of the Six Paths, yet both of them gained the TT's power not Hagoromo's. This came from the fact that the Six Paths (from the Six Paths Technique I believe), is just from Hagoromo's moniker. So, in other words to all characters in the series, the TT's power is considered Hagoromo's.

Regarding the similarities of both the TT's and Hagoromo's Chakra that most characters in the series thinks they are the same. One can only speculate but, we got the pieces to find the link between the two Chakras.

FIRST the whole residual Chakra thing. Gaara who lost Shukaku has Chakra very similar to Shukaku. Hagormo is no different. He was the Ten-Tails' Jinchuuriki (and the tailed beasts since he created them while the TT was inside him). SECOND is the fact that he is Kaguya/Ten-Tails' son. So, it's not weird that his Chakra is similar to her. THIRD is the fact that he had the so called Six Paths Senjutsu before becoming a Jinchuuriki. A power gained by the TT's Jinchuuriki (leaving Naruto for now), he had it without the TT. Means similar Chakra is what allowed him to do so.

This explains the similarities as well as why the Six Paths Chakra (His Chakra this time not the TT) was able to affect the TT's Jinchuuriki so easily (Sasuke bisecting Madara). If his Chakra isn't Senjutsu itself thanks to the TT's residual Chakra, then its has the same qualities once again thanks to the TT. Also Kaguya's use of the floating/levitation is because of this unique Chakra, we called it Six Paths something because of Kakashi's analysis, yet he is the same as Obito, thinking that the TT's power is Hagoromo's. So Kaguya's Chakra is very similar if not the same as Hagoromo's but, it was called Six Paths thanks to Hagoromo's deeds, not Kaguya's.
