Why are males more likely to be born?

Sbsbsbdnd
There seems to be like 3x more men than woman I noticed when um walking about in public. Why is it more likely for a mom to be become pregnant with a male instead of female?
Is there a reason for this in nature? Like maybe males are more useful?

Also almost all girls are taken and have a boyfriend, but there's tonnes of single. That's proof there's a limited amount of girls alive
