Bismillah, 

Asalamu Alaykom, 

No this is not the case. The Shia Muslims believe that the prophet Mohammad (sawa) who possesses prophethood, messengership and imamah, is the highest of all creation. Anyone saying otherwise is a deviant and ignorant. 
 

In a narration from Al-Kafi, Imam Ali (as) when asked by a Jew if he's a prophet, replied the following: 

إنما أنا عبد من عبيد محمد صلى الله عليه وآله

I am only an 'abd (slave) from the slaves of Mohammad (sawa). 
 

'Abd in this context means a servant or slave in the sense of complete obedience and not worship. The Quran also uses the word 'Abd for the non-worship sense too. Check 24:32. 
 

Therefore, despite the unfathomable status of Imam Ali (as), he shows that he is in a lower position as compared to Rasullah (sawa) by expressing his obedience and veneration to him. 
 

So then imagine the status of rasullah when someone such as Ali expresses such a statement! 
 

May Allah grant you success
