This isn't really true.
"According to the National Center for Education Statistics, just 41% of first-time full-time college students earn a bachelor’s degree in four years, and only 59% earn a bachelor’s in six years."

In contrast, these are MOOC completion rates:
>Among all MOOC participants, 3.13 percent completed their courses in 2017-18, down from about 4 percent the two previous years and nearly 6 percent in 2014-15.

They add:
>Certainly 55,000 people got access to education they might not otherwise have had. But "rather than creating new pathways at the margins of global higher education," the authors write, "MOOCs are primarily a complementary asset for learners within existing systems."
They do allude to a construct called "Verfied Students" which I have no idea about, which have higher but significantly varying completion rates.
> And among the "verified" students, 46 percent completed in 2017-18, compared to 56 percent in 2016-17 and about 50 percent the two previous years.
I have never encountered how that cohort was constructed, however if we are to start breaking down sub groups of students from general numbers, your data shows that non-profit and public institutions have near 60% graduation rates at 6 years.
In general a random student will more will likely graduate from a college, than a random person starting a MOOC.
