US new hire question: Help in understanding the number of leaves I would have in 2025

I will be starting employment at Seattle on 21st July. I see that in the 1st year, I am eligible for 128 hours of leaves. I have heard of Flexible PTO and Standard PTO being separated. Could someone explain to me if I get the 128 hours full in 2025, or is that prorated to the number of days I work in 2025? Also, how would that be ssparated between Flexible and Standard PTO?
