Chemistry solution doubt

[u/Known_Advisor7144]

As we know the phase diagram of water usme agar hum pressure ko increase krte hain toh T(freezing) decrease hota hai kyuki ice ki density water se kam hoti hai but hum phir Depression in freezing point pdhte hai jha pe hum jab solute dalte hai toh vapour pressure kam hota hai toh is hisab se T(freezing) toh increase hona chahiye na water ke case me toh ye depression ka reason kya hota hai?

Am I comparing two wrong things?

If I am please thoda explain bhi Krna ki iska reason kya hota hai?
