There are at least 2 ways I can think of for rigging a roulette wheel. If you alter how the table balances (such as putting something small and unnoticeable under two of the legs) then you'll probably find there is a greater chance the ball ends up on one side of the wheel than the other (or clusters around certain specific numbers) - there could even be a way to do this with two opposite legs out of alignment (on the diagonal) so a host or someone off camera can change the lean of the table every so few spins without being noticed.
There's also a possibility grooves could be added to parts of the wheel where the ball spins so its course changes as it roles (if you think of the bounce of a ball that hits a corner then it's a lot more predictable). There's probably a lot of people on both sides of a casino trying to look for these sorts of things though because it can hurt the house's edge if the wheel is a bit more predictable.
These both don't guarantee a specific number is hit though so it'll still make the outcome seem random (if not done in a way that's noticeable - someone stretching across the table to do more than pick up the ball would likely be perceived as weird at best).

Of course, anything created by humans can be manipulated bro, including roulette in physical casinos.
It could be that it was indeed rigged but no one knows for sure if it was really rigged, because it's about gambling isn't it?
In gambling some people will definitely experience victory or even defeat. It's a common thing.
It's simple if you lose and you are not comfortable with the game then switch to another game that makes you enjoy the game.
Obviously you are not comfortable playing at that casino, maybe you should try visiting another casino and try other luck that makes you comfortable.
If you keep thinking you are always being cheated on, then you will spend your time worrying all the time, right?
