> 99% of projects

I don't know where you got this figure from, but I highly doubt 1% of Rust projects use a different build/package system. More like 0.001% (this number is scientifically extracted from thin air).

99% in this context is an expression of speech.

OP doesn't literally mean 99%, they mean "almost everyone". The actual numerical value is irrelevant.

Most rust projects with special deps (libtorch) need another build manager.

Regardless parent was implying that almost everyone everywhere uses cargo.
