Does God only bless some?

Alex • Pregnant with baby #1 due date is May 30th. My beautiful rainbow baby.
It gets on my nerves that some people will say "God blessed us" when something good happens in their life. Does that mean that people who aren't as fortunate aren't as blessed. As to some way say that he's playing favorites? I feel like it's religious people's way of bragging without making them look bad. Does anyone else feel this way?
