There's no way that it's as high as 62%.
If 27 players on a fully-funded DI roster have to receive 25%, that leaves only 4.25 scholarships to be spread around to those who receive more than the minimum 25%. If the 27 shared the 11.7 scholarships equally (which, of course, they don't), everyone would receive 43%.
I'll leave it to those more current than I to update what I'm about to write; but, I've always carried around a rule-of-thumb that position players tend to receive between 25% and 50%, active relievers would receive something above 50%, and starting pitchers somewhere in the neighborhood of 75%.
However, just as obviously, it depends upon the program, the composition of the roster, and whether or not the program were fully funded to gain a better, more specific feel.
The best thing to do is to speak directly with recruiters about their program's scholarship characteristics, assuming that the program is relevant to the player's playing abilities and academic standing.
