No, it takes a lot more than a master's degree. Even a PhD is only really entry-level. There's no substitute for practical experience and talking to someone very experienced. Shame there aren't a lot more very experienced statisticians and data scientists out there.

Shame there aren't more concert pianists out there... but given the leverage big data can give (a small percentage change in what a big organization does can still save or earn big bucks) this is a competitive position, just as playing concerts is only for the few.

You want a better employee than your competitors have. You'll take all the expertise you can get, plus the ability to invent new techniques as needed. Everybody wants the very best 'cause that last 1% of skill can still be worth a lot of money. Everybody wants someone who can hit a lot of long balls for their team, as it were. There might be a floor on the skill level you could make some use of, but there's no ceiling.
