uncleanliness and sin are two different things entirely. Is it not true that an unclean person can not come into the presence of God? Can a sinful person come into the presence of God ?
Was the need of the cleansing by the blood of the sacrificed animal not a foreshadow of Christ and our need for Him to cleanse us?

Absolutely, but uncleanliness and sin are still different. Is a woman who menstruates sinning?
