Is that normal for you?

Is that a Shimano crank in a Mega EXO bottom bracket? You might need some spacers to make sure the crank doesn’t move around.

Normal.
You should see every square taper bb in existence. Gaps for days.

You have a sealed cartridge bearing down there. What little dirt and crud makes its was between the gap will not penetrate the seal.
It will need to severely impacted, loaded to the max, crammed like you were packing a suitcase, full of crud before you would have to worry.
