If you mean formal (university) education, it's rather not true because a diploma doesn't always guarantee you better career opportunities. Investing in learning some practical and applicable skills can be very fruitful of course.
I think you are missing the point. The contention from the topic is investing in education or in bitcoin.
For me it is better to invest in education first no matter how the level of the education is. Whether in primary, secondary or tertiary, it is better because it teaches how to read, write etc even though education has nothing to do with success but you can invest in different areas including bitcoin.
