125k is pretty good, isn't it? 8 years into my career I was at 60k. If you want to earn more then go for it, but you shouldn't feel bad about yourself.
My FAANG total comp was >150k (2015, new grad, major US metro area), and that was just the regular offer they made to everyone if you didn't try to negotiate.
You can definitely go higher, at least once the current coronavirus hiring freezes get lifted.
Where are you located? The numbers are way off compared to total compensation in FAANG. A software engineer in the level immediately above junior (2-3 years experience) earns ~250k at Google or Facebook in San Francisco: https://www.levels.fyi/#
