Absolutely & definitely not. Maybe the Classic Player might be (debatable), but not the Classic Series 60s. That's why I like them. I have one CS60s Strat neck on my partscaster & two CS60s Tele necks, one to replace an MIJ neck (too fat) & the other to replace the maple neck on an MIM Thinline. I had a 1999 US Standard which I sold earlier this year - the main problem for me was that I didn't like the neck. So I did some side by side comparisons before I let it go. There is nothing I could describe as "fat" about the CS60s necks - they are remarkably close in profile to the old AVRI62 necks.
