In my little fleece flock I have 8 lambs, of which 5 are tup lambs and 3 ewe lambs. 1 of the ewe lambs is not going to be a breeder, so having tupped 9, I have only 2 ewe lambs to retain.

(Actually it's probably just as well - I don't think I'm going to be very good at culling my special little sheep

)
Last year I tupped 4 and got 3 ewe lambs, 2 tup lambs. (1 of which was good enough to use.)
I have also put my fleecey tup lamb onto 6 of our Dutch Texel commercial shearlings. I haven't tracked down all of the offspring yet (the 6 are running with all the other shearlings, and BH is looking after that group), but the 3 ewes that have lambed so far that I've found have 4 tup lambs and 2 ewe lambs between them.

We put our Old Boy (oldest Texel tup) on the Mules and some of the Mule x Texel ewes, wanting some of the offspring to retain. I do know that every time one of the ewes I like lambs, both her lambs are boys

So my impression is that yes, we have more tup lambs than ewe lambs this year.
There is a theory that a tup (and same for a bull) produces more female offspring when he's younger, and more male offspring when he's older. Not sure I can confirm that theory, mind.
