In terms of units sold, it's actually correct. From the wikipedia page "List of best-selling game consoles"[0] I've taken the three from that generation:

1. Wii: 101.63 million

2. PS3: 87.4 million

3. Xbox 360: 84 million

It's possible the Xbox 360 dominated within your friend-group or even your locale (fwiw I didn't know anyone who had a 360, my friends who had a console had a PS3) but in terms of raw sales it's edged by PS3 and obliterated by the Wii.
