Does mousepad really matter for aim?

The title, i play cs2 alot and recently saw some videos saying mousepad affects the aim, but my current cheap Redgear mousepad feels fantastic, I was browsing through good mousepad yesterday and they all cost 1.5K+ , is it all placebo or if i were to upgrade will i notice the difference? If so any suggestions for under 2K ? ( Considering the reall humid conditions and wanted a control mousepad if i were to buy )
