I'd wager as much.

Consoles and gaming PCs tend to be expensive (in terms of upfront costs), require more physical space to use, and are hard to move.

Mobile phones have multiple purposes and, crucially, are mobile (shocker, right?)

This means that if you could only have 1 electronic device, you'd 100% choose a mobile phone.

And what better way to find a lot of customers than a F2P mobile game? It has 0 barrier to entry, a large audience, relatively low development costs, and little actual "game design" expectations.
