At least some people say yes, but it could be useful or interesting to talk about why you ask and what difference you see between knits and knots. Perhaps it depends on how one defines “knot”, but it seems like most definitions I can find work for a knit sweater.

These first two links talks about a knit being a series of knots - slip knots specifically. The other two suggest a knit is a very long knot.
