Do non-scholarship athletes have access to the same benefits as scholarship athletes?

To a degree, they do. Remember, participants in programs that do not offer athletic scholarships may not reap the benefits of a college athletics experience that is partially or fully funded, but the support for these (non-scholarship) programs in athletic departments is typically strong.

The lack of scholarship funding does not, in most cases, diminish the experience; it is just on a slightly different level.

Athletic departments at scholarship schools are generally better funded because of strong inter-conference competition and revenue producing sports. That being said, non-scholarship athletic departments have lately begun to place a high premium on fundraising in an effort to narrow the budget gap, and thereby heighten the student-athlete experience.
