Could someone give me the preflop odds of 4,3o beating T,T?

Which is exactly what happened to me at casino weds night.

$1/2 ring game at the local casino. 10 seated

$2,$2, then I made it $12 with my T’s on my turn. I got 2 callers neither in the blinds or the 2 original bettors.
Flop was 4,J,4 rainbow. I was first to act. I threw out $20 in chips, to see where I was at in the hand. 1st guy folded. 2nd guy said, “make it fifty.”
I said, “It’s yours,” and threw in my cards.
He turned over 3,4o

I did nothing wrong here right?

Don’t forget the odds.
