I don't quite agree with your statement. Most likely, your experts did not take into account that if a gambler has a lot of summary time for analytics or is completely immersed in sports betting (a professional bettor), then the number of his bets, on the contrary, can positively affect the number of winnings. This can be compared to an investment. For example, you can invest money in only one asset, or you can invest in 5. With the right approach, investing in 5 assets can yield a more significant profit. The same thing happens in betting - one winning bet can cover the losses from two lost ones.
There's no problem if you think that way. However, there are gamblers that just love to make a lot of bets which they can't even study the bets they are making, the increase of bets is just due to excitement they'll like to achieve, but in reality, the chances of wining is just neglected.
You have more bets to make, you also have more time to spend, it should go together, otherwise, it will not work.
The actions of each gambler will make the decision to take on so many bets a mistake or the right decision, profitable gamblers can definitely take on more bets because they know a particular sport like the back of their hand and they can analyze a match many times faster than most gamblers, however if a regular gambler were to do the same, this will be a mistake, since there is no way they can imitate the knowledge and the performance of a profitable gambler and they will just lose their money even faster than usual if they tried to do this.
