I don't know where you work, but this seems like a weirdly racist thing to say.
Based on my experience, it's also complete bullshit.
I work at a chip company in the US. Our (chip engineering) workforce is probably about half White Americans. The other half are predominantly Indian, with significant numbers of other Asians. (It's also almost entirely male, because 2018.)
At my previous employer, also a chip company in the US, the workforce was even more heavily skewed to White Americans. Probably at least 70%.
I can point to a great number of very smart, hard-working, dedicated, and capable co-workers in every one of these racial groups.
