Incorrect. That's not Musk's stated goal. What he said was:

"Building 100 Starships/year gets to 1000 in 10 years or 100 megatons/year or maybe around 100k people per Earth-Mars orbital sync" - [0]

Nothing at all about having a million people on Mars in 2050. To get a million people to Mars requires ten Earth-Mar orbital syncs, or 20 years. Adding 10 years to get to that 1000 Starships/year cadence. That means they have to achieve 100 Starship/years by 2022 to have a shot at sending a million people to Mars by 2052 (because the next orbital sync is 2022)

Starship hasn't flown yet with the first orbital flight hopefully some time next year. It will be well into 2020s, at the earliest, to get to 100 starships/year production rate. Musk knows that and he didn't state otherwise.

Reaching Mars in 4 years is the goal. He has always thought that was a stretch goal, as has been clear on every single presentation he has given on the topic. (BTW, NASA has a stretch goal of 2024 for landing people on the Moon; they acknowledge it is a stretch goal, and it probably also will be years later. Does that make NASA liars?)

But I'd say there's a greater than 50/50 chance of SpaceX landing people on Mars in Musk's lifetime. But that's not even THAT remarkable... Their actual goal (self-sustaining Mars civilization of at least a million people) is 5-6 orders of magnitude grander than that, and almost certainly won't occur in Musk's lifetime. Musk acknowledges that.
