If an event has 1 in 3,000 outcomes chance to happen, would it be correct to assume that it should actually occur AFTER I bet 3,000 times?

In other words, does probability starts and finishes with my own bets?

If the answer is no, which means that probability is irrelevant of if/what I'm betting, then imagine the following;

I have bet just 100 times and at that time happens an event with astronomical probability, this is not strange because let's say a casino works 24/7, has many wheels and there are many casinos like it around the world, therefore it would be accurate to assume that every single week, at a casino around the world, an astronomical probability event happens.

Or to put it another way, a very rare event happens at a particular casino every month, just imagine how many results happen per day, per casino...whether you were on your first visit at that casino or a regular patron the possibility of such event doesn't alters, regardless if you were betting or not and what would you bet.

So my conclusion is that what happens will happen regardless of our observations and what we would bet, do you agree?

Let me give you another example, let's say I start charting and notice that 1 number is above average and an EC is below average, I decide to bet both of them, my charting includes something like 100 spins, what if we had the whole results' record for that particular wheel?

We could notice that the specific number is far below average in overall and the 18 numbers EC group is far beyond average in overall.

My observations were for just 100 spins, are more valid indication from a much greater total??

What I'm trying to say is that we just see a tiny chunk of results and what we observe could be just a minor regression while we perceive it as a great deviation, the exact opposite!

Charting could be very misleading, especially regarding totals.

We can see a "tree" and miss a whole "forest"...so if we would discard past results all together what has left to gain an insight about what's coming up?

Another example, I'm betting High, Red and Even simultaneously, on the same table, what are the chances to win or lose all, what is the possibility of either winning or losing 2 out of 3?

Another example, again betting 3 ECs but this time on 3 different tables, what is my chance to win/lose all 3, what's the probability of win or lose 2 out of 3?

Are those 2 cases same in regards to probability?

In both there are 3 18 numbers bets, the only difference is that the first case takes place on 1 table and the second on 3 different.
