As far as I know, Snowflake is used to generate tweet IDs. Do you have any reason to believe that it's being used to generate user IDs?
As evidence against this, note that the ID density currently being produced for tweets is very, very low: when I collect from the sprinkler, I rarely get a tweet ID where the sequence number portion is much higher than 2 or 3. That is, almost all of the 12 bits of sequence number are 0, almost all the time. So the ID density for tweets is well under 1%. (And the sampling method Twitter is using to produce the sprinkler doesn't have an effect here, as far as I can work out.)
If Snowflake were being used to generate user IDs, I'd expect even lower ID densities. This doesn't jibe at all with 86% (or 82%) or anywhere close to it.
Dunno about Canada, but in the US a fixed-rate mortgage is, well, fixed. My rate will never change, and thus my monthly payment will remain exactly the same for the 30-year life of the loan.
