Actually, Pitt's average SAT for 2018-19 was 1348, with an average composite ACT of 30.5. UCF's average SAT was 1181 with a composite ACT of 26. That is from the respective schools' own Common Data Sets.
US News rankings determine whether a school is a diploma mill or not. Diploma mills are institutions that over prioritize revenue coming from large enrollments thereby losing quality control of the degrees they award. WVU isn't one because their historic mission to educate any willing student in one of the poorest states in the union which dictates that they'll never be able to climb rankings of arbitrary methodologies. Much higgher ranked schools than WVU are absolutely diploma mills. There are many ways they hide their true institutional admissions numbers in pursuit of tuition revenue and game the rankings.
But undergraduate admissions scores are only one very small aspect of a major university. A large part of the academic reputation of a research institution like Pitt is made on the graduate level, where the overall faculty reputation is based on research productivity and impact. And in research fields, even undergraduates are advantaged by being in an environment with a plethora of diverse, cutting edge opportunities. To that end, Pitt is the 16th largest academic R&D complex in the nation, the 9th most competitive for the most prestigious funding sources, and is the 4th most in the biomedical health sciences. For comparison, UCF is 98th, 113th, and 225th, respectively. What that 181 extra years also gets you is a $4.2 billion endowment, which goes a lot further with Pitt's smaller enrollment than UCF's $0.0002 billion endowment. It also lets you achieve top 10 reputations in academic fields like philosophy and the health sciences that take decades and decades to build, not to mention allows you to collect a few national championships along the way. And even with UCF's significant advantages in state public subsidization, over a time period of public support that is only two years shorter than Pitt's, there is little danger of a significant narrowing of those gaps any time soon.
