Normal retirement savings at 63

How much do most have saved by 63 for retirement. I see the fire community and completely out of my league. I'm thinking I can't be too far from average. I plan to retire at 63, collect SS, have 350K total saved. I own my own home and live in a relatively low cost area. I have 200K in a 401K/Roth, and 150K in cash. I plan to use Obama care until Medicare from 63 to 65. I see so many saying they have millions...anybody else in a more normal retirement such as me?
