Oh no, god is very real to people. I think I've mentioned before that my parents are kind of non-religious, yet my mom believes in one particular deity (in one specific temple), and when my dad was having his bypass surgery, pledged certain pujas if everything turned out okay. And dad says, mostly jokingly, that he asks for extensions from Shiva, seeing as to how he's the destroyer. My ILs are observant. My MIL goes to temple as often as possible, my SIL goes at least daily (the temple is right behind their house), and attributes to god the fact that she's never lost a patient, mother or child, in the 20+ years she's practiced. I think the difference might be that each person might believe in a different god than the next, or might pray to one during certain sets of circumstances than another.
You know how people put money on a plate during service? Over there, people put money in a big box that's bolted to the floor. Some temples are so popular, they can't make a box big enough, so they've cordoned off areas with fabric (imagine giant "boxes" constructed from fabric, several feet high, long, wide, etc. with open top), because people take off all their jewelry and toss in. Now, that's devotion for you.
As an aside, this particular god borrowed money from a money lender to pay for a lavish wedding is up to his eyeballs in debt, and needs money, and needs it now. He doesn't care how you made it, so he's particularly popular with business people, corrupt politicians, etc.
