Google the topic and you will find lots of info on this. For instance, see this analysis of the 2023 draft class:

131 out of the 259 draft picks (49.4%) were rated 4-stars out of high school by at least one recruiting service. That might not seem impressive, but 4- and 5-star players make up just 9.4% of the scholarship player pool on an annual basis.

4- and 5-star prospects are about 30-times more likely to be first-round picks than all other D1 scholarship recruits.

The correlation between high recruiting rankings and NFL Draft success, in addition to college team success, remains strong and is growing annually.
