It's "equal access", not "equal numbers". The "participation rate" is the key caveat there. It takes into account the number of high school boys participating in sports vs high school girls. Boys have always had a higher participation rate than girls. This is largely due to football and there being no female equivalent that fields that many players along with there being very few females participating in boys' football.
From what I'm finding, the participation ratio has ranged 70%-75% over the past two decades, so theoretically, a school would need to stay in that range when handing out athletic scholarships. So, for every 10 men's sports scholarships, a school would have about 7 women's sports scholarships. So, when you look at it, while football eats up a lot of men's scholarships in college, it being a huge source of high school athlete boys is a big reason why men are afforded more athletic scholarships than women (as a raw number).
Right now, if you look at the NCAA sports Mississippi State sponsors and the number of scholarships on each, there are 131.3 men's scholarships and 85 women's scholarships (so about a 65% ratio).
