how much important is MSBI for a web developer/freelancer?

Question

Do i need to be an expert of MSBI (SSRS, SSIS, Power BI, SQL, SSAS, and MDX) in order to complete a project by my own.

As a web developer i know SSRS but i have very little idea of other pillars of MSBI , i want my career to go in simple one direction i.e web development (html,css,js, Asp.net,Azure, sql ,angular etc), if i give 2 hours daily on MSBI learning then i will be good at MSBI in a month or two but does it add any value to my life?

Any guidence will be appreciated.
