No. Look at the frequency. It's 60Hz. You're just seeing noise from the AC line.
Amplitude is pretty big too. What do you have the ground of your scope connected to?

Get that frequency dialed in to more like 45kHz or higher so you can see the horizontal sync pulses.

It should look something like this.
