Your title pretty much says it all, one shouldn't gamble if they don't have patience of they will gamble away everything that they have since they wouldn't be able to control themselves in the middle of gambling and will eventually just spend every single dime they might have had just like you and regretting after that doesn't do any good at all.
If I was you, I would probably just get away from the platform for a while until the transaction is confirmed so that I can withdraw my funds, I have that kind of patience and I'm happy and proud that I do unlike many others who don't.
Good for you because you are quite well in-terms of managing your emotions, but we cannot really deny that there are a lot of gamblers out there who have the exact opposite attitude especially when they are on a streak like what the OP have said. OP have stated that while he was waiting for his transaction to go through his wallet, he was having a past-time in the same platform using $1 bet but he didn't foresee what will happen down the road as he was already sucked by his emotions.
IMO, it's not all about patience because partially, it is also about having a safe distance because the OP was just looking for a past time until the funds was credited to his wallet. He was just waiting and still playing because he got another transaction to do, which is already wrong because he could've done another thing for the meantime.
Not all would really be having that self control and not all would really be having that kind of discipline in towards things that they are currently dealing with specially with gambling on which we know that most likely
people would really be getting that impulsive on the time that they would really making out some engagement on which it is really that hard to point out fingers or blaming them on what they had done. As a human being
then its impossible that we cant really be able to assess on whatever actions that we are tending to do and this is where people would really be differing into each other because there are people
who do simply that ignore nor tolerate on what are the things that they do have in mind on the time that they do gamble.
Emotion reaction would really be totally differ into each person on which there are ones who are really good on handling it and there are ones who are really that impulsive which would
cause up lots of errors and mistakes along the way.
