There is no Bible injunction against gambling,

There sure is, it falls under "Thou shalt not covet".

I'll bet you a $1 I'm right on this one.

"Thou shalt not covet" doesn't prohibit, say, getting a college education in order to increase one's chances of earning more money. Looking for income is not the sin. The commandment is talking about the kind of attitude that raises earthly goods up on a pedestal, and envies if it can't get them -- keeping up with the Joneses.

Nope. Gambling became taboo in the Christian church because the Roman soldiers gambled for Jesus' clothes.

That's a stretch. "Thou shalt not covet" is only part of it. It goes on to say "thy neighbor's..." So it doesn't just generally say that we shouldn't covet, period. It says that we shouldn't covet what belongs to other people, as in "I wish that I owned that nice car instead of Jim."
