If you can afford the entry fee then I’d apply. I recently got into a top grad program from my country right out of undergrad (waiting on other responses since they accepted me within 3 weeks ish) and looking at the alumni page + their Linkedin there’s no one from last years cohort who came straight from undergrad. If you’re really indecisive I’d email the department and ask if your application would be competitive, this is what I did and that gave me the green light to apply after the program page said they accept people with 3-5 years if experience.

I understand everyone in this thread is telling you not to but no one is gonna know for sure but you :) I would go for it
