How many Aztecs fought against Cortes?

Alright. there were no actual soldiers of the Aztec empire. during the celebration they had. (The Aztecs thought they were gods because they had horses). But in the death toll there were almost 300,000 thousand people who had died. only 25 of Cortes 1000 men had died. Of course the Aztecs were defeated.

Why?

• Spanish Had Guns
• Aztecs had Sticks with Rocks at the end.
• Ya... Easy as that
