[Avengers: Infinity War] "Oh yeah, you're much more of a Thanos." What did Doctor Strange mean by this line?

Did he say it because Thanos turned out to be bigger/taller than he expected?

Dumb question I know. Every so often I think about this.

After receiving a warning from Banner about "Thanos is coming", Strange had met and fought two unfamiliar groups, the Black Order and the Guardians, not knowing what Thanos looked like.

Then he saw the actual Thanos and goes "Yeah, that looks like a galactic conqueror all right".
