Call me stupid but I was told that while yes, Trees does absorb CO2 form the air and give Oxygen back during daytime. There’s also a reason to not have tree in your enclosed bedroom during night as it release all the CO2 absorbed.
So my question was that people are saying to plant tree to help purify the air in streets, city, or any dense population location. If the statement in first paragraph’s correct. wouldn’t that just result in that the trees would give the o2 and purify the air during day time and just flood the street with co2 during night? I’m confused…

Think about this, what are trees made off?
They are made of essentially different compounds of carbon, hydrogen and oxygen. They get the hydrogen and some oxygen from water, and the carbon and rest of oxygen comes from co2 in the air.
So as long as a tree is growing and thus accumulating more biomass, they are capturing co2 from the atmosphere.
