It depends on your definition of rigged. There are many "provably fair" online casinos where they use hashes and user generated seeds that influence the outcome such that it makes it 100% verifiably fair but you will still lose over time because the house edge. If you call the house edge "rigged" then offline gambling is equally rigged
Offline casinos can also make money on drinks/snacks/entrance fee/hotels rooms. Theoretically it would be possible to run an offline casinos with loosing odds. (They don't)
Offline casinos have a much higher margin (called house edge) than online casinos. This is because they need to pay rent, business rates, salaries, security, etc. Online casinos can survive on a skeleton crew with a cloud based turn key solution. Thus their house edge is usually lower. The lower the house edge is, the more players win. The more players win, the more players you have.
