If you play your cards right, I think you could get into a top-20 school, maybe even a top 10. You say you were a humanities major? You have some experience in tutoring for writing and literacy. Do/did you have any literary interests, hobbies, achievements, goals? Plenty of physicians are also writers of fiction and non-fiction. Often they write about their experiences as scientists and clinicians. Some schools---esp. in top 20---have curricula to help physician writers meet their career goals, or they are located next to a great undergrad/grad campus, like Yale and UChicago. Anyway, this is just an example of how you can make yourself stand out a little as a non-traditional.
Because you're a non-trad, you will SINK or SWIM based on how you handle your essays. I mean, you'll perform much better or a little worse than the guy straight out of college, depending on the narrative you make for your candidacy. Do you spin yourself as the directionless quarter-life-crisis guy, or the eclectic, mature guy who has a focused and nuanced interest in medicine? It's up to you. I have plenty of non-trad pre-med friends. One has so-so stats and got into a top-5 school, the other had a 99.99 percentile MCAT and did not get into a single top-20 school. The former had a great story about his LGBT activism, and the latter really had no story besides a vague "I want to help people" narrative.
Because your application has such a wide spectrum of potential, I suggest applying broadly to 25-35 schools of all ranges. The more liberal/pro-humanities colleges are higher yield. (E.g., WashU low-yield, Yale and Columbia very high yield) For the lower tier schools, you should write in your essays why you would attend even though your stats are above them by a large margin. Otherwise they may just reject you because they think you are just making them a safety.
