Stockfish rates this +0.09, a tiny edge for White. That means you are basically equal here.

In the drill, focus on reliable development and on answering the centre in a principled way.
What the engine wants you to do
The engine’s best move here is d4, and the main continuation given is d4 d5 Bd3 dxe4. That tells you what this structure wants: immediate central tension rather than slow drifting. As Black, you should be ready for the centre to open quickly, and you should not be surprised if the game turns into a straightforward fight over space and piece activity.

The big picture is that White has several ways to continue, but none of them gives a clear practical refutation of your setup; your job is to know which ideas deserve respect and which ones can be met by accurate central play.
The moves that slip
Some White choices are already marked as errors. Nc3 is an inaccuracy and loses about 0.5 pawns, with d4 as the better move. d3 is also an inaccuracy and loses about 0.8 pawns, again with d4 as the better move. h4 is the biggest listed mistake and loses about 1.1 pawns, with d4 still the better move. In other words, if White wanders away from the centre, you should be alert for a chance to seize the initiative by meeting the position head-on.
