Numbers in redis can be natively represented using BITFIELDS.

> BITFIELD player:1:stats SET u32 #0 1000

1) (integer) 0

> BITFIELD player:1:stats INCRBY u32 #0 -900

1) (integer) 100

> BITFIELD player:1:stats GET u32 #0

1) (integer) 100

OK, that's helpful thank you.

That said, all the keys themselves are still strings and therefore you can't have a SET of numbers or bitfields.
